Move readline to the readline/readline subdirectory

readline turns out to be a bit of a stumbling block for the project to
move gdbsupport (and then gdbserver) to the top-level.

The issue is that readline headers are intended to be included with
names like "readline/readline.h".  To support this, gdb effectively
adds a -I option pointing to the top-level source directory -- but,
importantly, this option is not used when the system readline is used.

For gdbsupport, a -I option like this would always be needed, but that
in turn would break the system readline case.  This was PR build/17077,
fixed in commit a8a5dbcab8df0b3a9e04745d4fe8d64740acb323.

Previously, we had discussed this on the gdb-patches list in terms of
removing readline from the tree

    https://sourceware.org/ml/gdb-patches/2019-09/msg00317.html

However, Eli expressed some concerns, and Joel did as well (off-list).

Given those concerns, and the fact that a patch-free local readline is
relatively new in gdb (it was locally patched for years), I changed my
mind and decided to handle this situation by moving the readline
sources down a level.

That is, upstream readline is now in readline/readline, and the
top-level readline directory just contains the minimal configury
needed to build that.

This fixes the problem because, when gdb unconditionally adds a
-I$(top_srcdir), this will not find readline headers.  A separate -I
will be needed instead, which is exactly what's needed for
--with-system-readline.

-Introduction
-============
+This is an import of readline that is used by gdb.
 
-This is the Gnu Readline library, version 8.0.
+To send patches, follow the gdb patch submission instructions in
+../gdb/CONTRIBUTE.  For maintainers, see ../gdb/MAINTAINERS.
 
-The Readline library provides a set of functions for use by applications
-that allow users to edit command lines as they are typed in.  Both
-Emacs and vi editing modes are available.  The Readline library includes
-additional functions to maintain a list of previously-entered command
-lines, to recall and perhaps reedit those lines, and perform csh-like
-history expansion on previous commands.
+If you need to patch readline, please document the changes here.
 
-The history facilites are also placed into a separate library, the
-History library, as part of the build process.  The History library
-may be used without Readline in applications which desire its
-capabilities.
+To import, copy the upstream readline sources into the "readline"
+subdirectory, remembering to (1) remove any files that were deleted
+upstream, and (2) merge the one small configure.ac patch that gdb
+carries.
 
-The Readline library is free software, distributed under the terms of
-the [GNU] General Public License as published by the Free Software
-Foundation, version 3 of the License.  For more information, see the
-file COPYING.
-
-To build the library, try typing `./configure', then `make'.  The
-configuration process is automated, so no further intervention should
-be necessary.  Readline builds with `gcc' by default if it is
-available.  If you want to use `cc' instead, type
-
-        CC=cc ./configure
-
-if you are using a Bourne-style shell.  If you are not, the following
-may work:
-
-        env CC=cc ./configure
-
-Read the file INSTALL in this directory for more information about how
-to customize and control the build process.
-
-The file rlconf.h contains C preprocessor defines that enable and disable
-certain Readline features.
-
-The special make target `everything' will build the static and shared
-libraries (if the target platform supports them) and the examples.
-
-Examples
-========
-
-There are several example programs that use Readline features in the
-examples directory.  The `rl' program is of particular interest.  It
-is a command-line interface to Readline, suitable for use in shell
-scripts in place of `read'.
-
-Shared Libraries
-================
-
-There is skeletal support for building shared versions of the
-Readline and History libraries.  The configure script creates
-a Makefile in the `shlib' subdirectory, and typing `make shared'
-will cause shared versions of the Readline and History libraries
-to be built on supported platforms.
-
-If `configure' is given the `--enable-shared' option, it will attempt
-to build the shared libraries by default on supported platforms.
-
-Configure calls the script support/shobj-conf to test whether or
-not shared library creation is supported and to generate the values
-of variables that are substituted into shlib/Makefile.  If you
-try to build shared libraries on an unsupported platform, `make'
-will display a message asking you to update support/shobj-conf for
-your platform.
-
-If you need to update support/shobj-conf, you will need to create
-a `stanza' for your operating system and compiler.  The script uses
-the value of host_os and ${CC} as determined by configure.  For
-instance, FreeBSD 4.2 with any version of gcc is identified as
-`freebsd4.2-gcc*'.
-
-In the stanza for your operating system-compiler pair, you will need to
-define several variables.  They are:
-
-SHOBJ_CC	The C compiler used to compile source files into shareable
-		object files.  This is normally set to the value of ${CC}
-		by configure, and should not need to be changed.
-
-SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
-		position-independent code.  If you are using gcc, this
-		should probably be set to `-fpic'.
-
-SHOBJ_LD	The link editor to be used to create the shared library from
-		the object files created by $SHOBJ_CC.  If you are using
-		gcc, a value of `gcc' will probably work.
-
-SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
-		If you are using gcc, `-shared' may be all that is necessary.
-		These should be the flags needed for generic shared object
-		creation.
-
-SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
-		creation.  Many systems use the -R option to the link
-		editor to embed a path within the library for run-time
-		library searches.  A reasonable value for such systems would
-		be `-R$(libdir)'.
-
-SHLIB_LIBS	Any additional libraries that shared libraries should be
-		linked against when they are created.
-
-SHLIB_LIBPREF	The prefix to use when generating the filename of the shared
-		library.  The default is `lib'; Cygwin uses `cyg'.
-
-SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
-		generating the filename of the shared library.  Many systems
-		use `so'; HP-UX uses `sl'.
-
-SHLIB_LIBVERSION The string to append to the filename to indicate the version
-		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
-		and possibly include version information that allows the
-		run-time loader to load the version of the shared library
-		appropriate for a particular program.  Systems using shared
-		libraries similar to SunOS 4.x use major and minor library
-		version numbers; for those systems a value of
-		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
-		Systems based on System V Release 4 don't use minor version
-		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
-		Other Unix versions use different schemes.
-
-SHLIB_DLLVERSION The version number for shared libraries that determines API
-		compatibility between readline versions and the underlying
-		system.  Used only on Cygwin.  Defaults to $SHLIB_MAJOR, but
-		can be overridden at configuration time by defining DLLVERSION
-		in the environment.
-
-SHLIB_DOT	The character used to separate the name of the shared library
-		from the suffix and version information.  The default is `.';
-		systems like Cygwin which don't separate version information
-		from the library name should set this to the empty string.
-
-SHLIB_STATUS	Set this to `supported' when you have defined the other
-		necessary variables.  Make uses this to determine whether
-		or not shared library creation should be attempted.
-
-You should look at the existing stanzas in support/shobj-conf for ideas.
-
-Once you have updated support/shobj-conf, re-run configure and type
-`make shared'.  The shared libraries will be created in the shlib
-subdirectory.
-
-If shared libraries are created, `make install' will install them. 
-You may install only the shared libraries by running `make
-install-shared' from the top-level build directory.  Running `make
-install' in the shlib subdirectory will also work.  If you don't want
-to install any created shared libraries, run `make install-static'. 
-
-Documentation
-=============
-
-The documentation for the Readline and History libraries appears in
-the `doc' subdirectory.  There are three texinfo files and a
-Unix-style manual page describing the facilities available in the
-Readline library.  The texinfo files include both user and
-programmer's manuals.  HTML versions of the manuals appear in the
-`doc' subdirectory as well. 
-
-Usage
-=====
-
-Our position on the use of Readline through a shared-library linking
-mechanism is that there is no legal difference between shared-library
-linking and static linking--either kind of linking combines various
-modules into a single larger work.  The conditions for using Readline
-in a larger work are stated in section 3 of the GNU GPL.
-
-Reporting Bugs
-==============
-
-Bug reports for Readline should be sent to:
-
-        bug-readline@gnu.org
-
-When reporting a bug, please include the following information:
-
-        * the version number and release status of Readline (e.g., 4.2-release)
-        * the machine and OS that it is running on
-        * a list of the compilation flags or the contents of `config.h', if
-          appropriate
-        * a description of the bug
-        * a recipe for recreating the bug reliably
-        * a fix for the bug if you have one!
-
-If you would like to contact the Readline maintainer directly, send mail
-to bash-maintainers@gnu.org.
-
-Since Readline is developed along with bash, the bug-bash@gnu.org mailing
-list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
-Readline bug reports and fixes.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a

-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl    and used.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl    Catalog format: none
-dnl    Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.

+Introduction
+============
+
+This is the Gnu Readline library, version 8.0.
+
+The Readline library provides a set of functions for use by applications
+that allow users to edit command lines as they are typed in.  Both
+Emacs and vi editing modes are available.  The Readline library includes
+additional functions to maintain a list of previously-entered command
+lines, to recall and perhaps reedit those lines, and perform csh-like
+history expansion on previous commands.
+
+The history facilites are also placed into a separate library, the
+History library, as part of the build process.  The History library
+may be used without Readline in applications which desire its
+capabilities.
+
+The Readline library is free software, distributed under the terms of
+the [GNU] General Public License as published by the Free Software
+Foundation, version 3 of the License.  For more information, see the
+file COPYING.
+
+To build the library, try typing `./configure', then `make'.  The
+configuration process is automated, so no further intervention should
+be necessary.  Readline builds with `gcc' by default if it is
+available.  If you want to use `cc' instead, type
+
+        CC=cc ./configure
+
+if you are using a Bourne-style shell.  If you are not, the following
+may work:
+
+        env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process.
+
+The file rlconf.h contains C preprocessor defines that enable and disable
+certain Readline features.
+
+The special make target `everything' will build the static and shared
+libraries (if the target platform supports them) and the examples.
+
+Examples
+========
+
+There are several example programs that use Readline features in the
+examples directory.  The `rl' program is of particular interest.  It
+is a command-line interface to Readline, suitable for use in shell
+scripts in place of `read'.
+
+Shared Libraries
+================
+
+There is skeletal support for building shared versions of the
+Readline and History libraries.  The configure script creates
+a Makefile in the `shlib' subdirectory, and typing `make shared'
+will cause shared versions of the Readline and History libraries
+to be built on supported platforms.
+
+If `configure' is given the `--enable-shared' option, it will attempt
+to build the shared libraries by default on supported platforms.
+
+Configure calls the script support/shobj-conf to test whether or
+not shared library creation is supported and to generate the values
+of variables that are substituted into shlib/Makefile.  If you
+try to build shared libraries on an unsupported platform, `make'
+will display a message asking you to update support/shobj-conf for
+your platform.
+
+If you need to update support/shobj-conf, you will need to create
+a `stanza' for your operating system and compiler.  The script uses
+the value of host_os and ${CC} as determined by configure.  For
+instance, FreeBSD 4.2 with any version of gcc is identified as
+`freebsd4.2-gcc*'.
+
+In the stanza for your operating system-compiler pair, you will need to
+define several variables.  They are:
+
+SHOBJ_CC	The C compiler used to compile source files into shareable
+		object files.  This is normally set to the value of ${CC}
+		by configure, and should not need to be changed.
+
+SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
+		position-independent code.  If you are using gcc, this
+		should probably be set to `-fpic'.
+
+SHOBJ_LD	The link editor to be used to create the shared library from
+		the object files created by $SHOBJ_CC.  If you are using
+		gcc, a value of `gcc' will probably work.
+
+SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
+		If you are using gcc, `-shared' may be all that is necessary.
+		These should be the flags needed for generic shared object
+		creation.
+
+SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
+		creation.  Many systems use the -R option to the link
+		editor to embed a path within the library for run-time
+		library searches.  A reasonable value for such systems would
+		be `-R$(libdir)'.
+
+SHLIB_LIBS	Any additional libraries that shared libraries should be
+		linked against when they are created.
+
+SHLIB_LIBPREF	The prefix to use when generating the filename of the shared
+		library.  The default is `lib'; Cygwin uses `cyg'.
+
+SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
+		generating the filename of the shared library.  Many systems
+		use `so'; HP-UX uses `sl'.
+
+SHLIB_LIBVERSION The string to append to the filename to indicate the version
+		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
+		and possibly include version information that allows the
+		run-time loader to load the version of the shared library
+		appropriate for a particular program.  Systems using shared
+		libraries similar to SunOS 4.x use major and minor library
+		version numbers; for those systems a value of
+		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
+		Systems based on System V Release 4 don't use minor version
+		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
+		Other Unix versions use different schemes.
+
+SHLIB_DLLVERSION The version number for shared libraries that determines API
+		compatibility between readline versions and the underlying
+		system.  Used only on Cygwin.  Defaults to $SHLIB_MAJOR, but
+		can be overridden at configuration time by defining DLLVERSION
+		in the environment.
+
+SHLIB_DOT	The character used to separate the name of the shared library
+		from the suffix and version information.  The default is `.';
+		systems like Cygwin which don't separate version information
+		from the library name should set this to the empty string.
+
+SHLIB_STATUS	Set this to `supported' when you have defined the other
+		necessary variables.  Make uses this to determine whether
+		or not shared library creation should be attempted.
+
+You should look at the existing stanzas in support/shobj-conf for ideas.
+
+Once you have updated support/shobj-conf, re-run configure and type
+`make shared'.  The shared libraries will be created in the shlib
+subdirectory.
+
+If shared libraries are created, `make install' will install them. 
+You may install only the shared libraries by running `make
+install-shared' from the top-level build directory.  Running `make
+install' in the shlib subdirectory will also work.  If you don't want
+to install any created shared libraries, run `make install-static'. 
+
+Documentation
+=============
+
+The documentation for the Readline and History libraries appears in
+the `doc' subdirectory.  There are three texinfo files and a
+Unix-style manual page describing the facilities available in the
+Readline library.  The texinfo files include both user and
+programmer's manuals.  HTML versions of the manuals appear in the
+`doc' subdirectory as well. 
+
+Usage
+=====
+
+Our position on the use of Readline through a shared-library linking
+mechanism is that there is no legal difference between shared-library
+linking and static linking--either kind of linking combines various
+modules into a single larger work.  The conditions for using Readline
+in a larger work are stated in section 3 of the GNU GPL.
+
+Reporting Bugs
+==============
+
+Bug reports for Readline should be sent to:
+
+        bug-readline@gnu.org
+
+When reporting a bug, please include the following information:
+
+        * the version number and release status of Readline (e.g., 4.2-release)
+        * the machine and OS that it is running on
+        * a list of the compilation flags or the contents of `config.h', if
+          appropriate
+        * a description of the bug
+        * a recipe for recreating the bug reliably
+        * a fix for the bug if you have one!
+
+If you would like to contact the Readline maintainer directly, send mail
+to bash-maintainers@gnu.org.
+
+Since Readline is developed along with bash, the bug-bash@gnu.org mailing
+list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
+Readline bug reports and fixes.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value `$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+\`configure' configures readline 8.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
