Remove includes reported as unused by clangd. Then, add any includes
necessary to get rid of errors (includes possibly relying on previous
includes)..
I didn't remove the includes of gdb-safe-ctypes.h, because it appears to
do some some preprocessor magic. I'm afraid that removing these
includes could change the behavior unintentionally.

It seems like gdb_curses.h is included whenever we want to access
ncurses functionality, instead of including directly ncurses.h. As a
result, clangd often erroneously shows that gdb_curses.h inclusions are
unused.
By adding those pragmas, clangd (and the include-what-you-use tool)
understands that gdb_curses.h is a valid provider for whatever these
ncurses.h files provide.

While preparing the new release it was discovered that commit:
commit 824083f34c222aa7419e2ea58e82d6f230d5f531
Date: Fri Apr 12 17:47:20 2024 +0100
gdb/doc: use silent-rules.mk in the Makefile
was causing problems. Given a release tar file, an attempt to build
and install GDB would give an error like this:
[...]
TEXI2POD gdb.pod
cannot find GDBvn.texi at ../../../gdb-15.0.50.20240508/gdb/doc/../../etc/texi2pod.pl line 251, <GEN0> line 16.
make[5]: *** [Makefile:663: gdb.pod] Error 2
The problem here is how the man pages are built, and how they are
distributed within a release.
Within the development (git) tree, the man page files are not part of
the source tree, these files are built as needed. Within a release
tar file though, the man pages are included. The idea being that a
user can build and install GDB, including getting the man pages,
without having to install the tools needed to generate the man pages.
The man pages are generated in a two step process. First the .texi
file is processed with texi2pod to create a .pod file, then this .pod
file is processed to create the .1 or .5 man file.
Prior to the above commit these two steps were combined into a single
recipe, this meant that when a user performed a build/install from a
release tree all of the dependencies, as well as the final result,
were all present in the source tree, and so nothing needed to be
rebuilt.
However, the above commit split the two steps apart. Now we had a
separate rule for building the .pod files, and the .1/.5 man page
files depended on the relevant .pod file.
As the .pod files are not shipped in a GDB release, this meant that
one of the dependencies of the man page files was now missing. As a
result if a user tried to install from a release tree a rebuild of the
.pod files would be attempted, and if that succeeded then building the
man pages would follow that.
Unfortunately, building the .pod files would fail as the GDBvn.texi
file, though present in the source tree, was not present in the build
tree, which is where it is needed for the .pod file generation to
work.
To fix this, I propose merging the .pod creation and the .1/.5 man
page creation back into a single recipe. Having these two steps split
is probably the "cleaner" solution, but makes it harder for us to
achieve our goal of shipping the prebuilt man page files. I've added
a comment explaining what's going on (such a comment would have
prevented this mistake having been made in the first place).
One possibly weird thing here is that I have left both an
ECHO_TEXI2POD and a ECHO_TEXI2MAN in the rule $(MAN1S) and $(MAN5S)
recipes. This is 100% not going to break anything, these just print
two different progress messages while executing the recipes, but I'm
not sure if this is considered poor style or not. Maybe we're only
supposed to have a single ECHO_* per recipe?
Anyway, even if this is poor style, I figure it really is just a style
thing. We can tweak this later as needed. Otherwise, this commit
should fix the current issue blocking the next GDB release.

The code that was factored out from gdb.base/relativedebug.exp assumed that
libc has debug info and only determined that it doesn't if it saw a specific
message from GDB to that effect. In the process of factoring it into a
require predicate, I made it stricter by trying to make a specific
determination of whether or not debug info is available.
Pedro noticed that "It'll disable the testcase on systems that link with
their libc statically (even if has debug info), or systems that name their
libc something else." Which is something I hadn't considered.
This patch returns libc_has_debug_info to the original behaviour.
Also, remove a verbose message that is redundant with the $message
variable.

When running test-case gdb.testsuite/gdb-caching-proc-consistency.exp with

The added check fixes the case when an unqualified lookup
name without template arguments causes expansion of many CUs
which contain the name with template arguments.
This is similar to what dw2_expand_symtabs_matching_symbol does
before expanding the CU.
In the referenced issue the lookup name was wxObjectDataPtr and many
CUs had names like wxObjectDataPtr<wxBitmapBundleImpl>. This caused
their expansion and the lookup took around a minute. The added check
helps to avoid the expansion and makes the symbol lookup to return in
a second or so.

The 'univeral_compile_options' in gdb.exp file only verifies the support
of '-fdiagnostics-color=never' for the "C" source file. So while running
tests with assembly source file (.s), many of them are not able to run
on icx/clang compilers because '-fdiagnostics-color=never' option is not
supported. This problem is not seen for the ".S" assembly source files so
these files are not handled separately. After this change, this function
is split into multiple functions to check the support for different type
of sources individually.
Before this change, in the case of clang and ICX compiler, this error is
shown for assembly source files (.s):
'''

This happens because packet_result::m_textual_err_msg is uninitialized

gets copied, an invalid value for m_textual_err_msg (a bool field) is
loaded, which triggers ubsan.

Currently, if you configure gdb with explicit --enable-threading, but
then configure detects std::thread does not work, configure silently
disables threading support and continues configuring.
This patch makes that scenario cause a configuration error, like so:
$ /home/pedro/gdb/src/configure --enable-threading && make
...
configure: error: std::thread does not work; disable threading
make[1]: *** [Makefile:11225: configure-gdbsupport] Error 1
make[1]: Leaving directory '/home/pedro/gdb/build-windows-threads'
make: *** [Makefile:1041: all] Error 2
$
Additionally, if you don't explicitly pass --enable-threading, and
std::thread does not work, we will now get a warning (and the build
continues):
$ /home/pedro/gdb/src/configure && make
...
configure: WARNING: std::thread does not work; disabling threading
...
This is similar to how we handle --enable-tui and missing curses. The
code and error/warning messages were borrowed from there.

Currently names like "x::y::z<1>" and "x::y::z<0x01>" canonicalize to
different things. I think it's nicer for them to be the same.
Differences between types can be done using suffixes like "ll" and "u"
-- it's not really possible to implement C++ rules in the
canoncalizer, because no gdbarch is available. Possibly gdb should
even drop the type here and just represent all integers the same way
in names.
