This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

This patch mostly aims at fixing a GDB build failure on 32bit Solaris
systems (Sparc and x86), due to a recent gnulib update adding the
readlink module. But it might also fix related issues when configuring
with --disable-largefile.
A side-effect of the gnulib readlink module addition is that it caused
largefile support to be added as well, and in particular
gnulib/import/m4/largefile.m4 introduced the following new #define in
gnulib's config.in:
| +/* Number of bits in a file offset, on hosts where this is settable. */
| +#undef _FILE_OFFSET_BITS
When defined to 64, it triggers an issue with procfs.h while trying
to build sparc-sol2-nat.c:
| #if !defined(_LP64) && _FILE_OFFSET_BITS == 64
| #error "Cannot use procfs in the large file compilation environment"
| #endif
As it turns out, this is a fairly familiar problem, and one of
the reasons behind ACX_LARGEFILE having been created. In that macro,
we have some code which disables largefile support on solaris hosts:
| sparc-*-solaris*|i[3-7]86-*-solaris*)
| changequote([,])dnl
| # On native 32bit sparc and ia32 solaris, large-file and procfs support
| # are mutually exclusive; and without procfs support, the bfd/ elf module
| # cannot provide certain routines such as elfcore_write_prpsinfo
| # or elfcore_write_prstatus. So unless the user explicitly requested
| # large-file support through the --enable-largefile switch, disable
| # large-file support in favor of procfs support.
| test "${target}" = "${host}" -a "x$plugins" = xno \
| && : ${enable_largefile="no"}
| ;;
But gnulib ignores this fact, and so tries to determine how to
enable large-file support irrespective of whether we want it or not.
This patch fixes the issue by passing --disable-largefile to gnulib's
configure when large-file support in GDB is disabled. This is done
by first enhancing ACX_CONFIGURE_DIR to allow us to pass extra
arguments to be passed to the configure command, and then by modifying
GDB's configure to pass --disable-largefile if large-file support
is disabled.
gdb/ChangeLog:
* acx_configure_dir.m4 (ACX_CONFIGURE_DIR): Add support for
new "EXTRA-ARGS" parameter.
* configure.ac: If large-file support is disabled in GDB,
pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib".
* configure: Regenerate.
gdb/gdbserver/ChangeLog:
* configure.ac: If large-file support is disabled in GDBserver,
pass --disable-largefile to ACX_CONFIGURE_DIR call for "gnulib".
* configure: Regenerate.
Tested by rebuilding on sparc-solaris and x86_64-linux (with gdbserver).
This fixes the build failure on sparc-solaris. I also verified in
gnulib's config.log file that we pass --disable-largefile in the solaris
case, while we do not in the GNU/Linux case.

Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
