18d2988e5d gdb, gdbserver, gdbsupport: remove includes of early headers
Now that defs.h, server.h and common-defs.h are included via the
`-include` option, it is no longer necessary for source files to include
them.  Remove all the inclusions of these files I could find.  Update
the generation scripts where relevant.

a197d5f7eb Really fix Windows gdbserver segment registers
My earlier attempt to mask the segment registers in gdbserver for
Windows introduced some bugs.  That patch is here:

https://sourceware.org/pipermail/gdb-patches/2023-December/205306.html

The problem turned out to be that these fields in the Windows
'CONTEXT' type are just 16 bits, so while masking the values on read
is fine, writing the truncated values back then causes zeros to be
written to some subsequent field.

This patch cleans this up by arranging never to write too much data to
a field.

I also noticed that two register numbers here were never updated for
the 64-bit port.  This patch fixes this as well, and renames the "FCS"
register to follow gdb.

Finally, this patch applies the same treatment to windows-nat.c.

1d506c26d9 Update copyright year range in header of all files managed by GDB
This commit is the result of the following actions:

  - Running gdb/copyright.py to update all of the copyright headers to
    include 2024,

  - Manually updating a few files the copyright.py script told me to
    update, these files had copyright headers embedded within the
    file,

  - Regenerating gdbsupport/Makefile.in to refresh it's copyright
    date,

  - Using grep to find other files that still mentioned 2023.  If
    these files were updated last year from 2022 to 2023 then I've
    updated them this year to 2024.

I'm sure I've probably missed some dates.  Feel free to fix them up as
you spot them.

213516ef31 Update copyright year range in header of all files managed by GDB
This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

801eb70f9a Fix gdbserver build for x86-64 Windows
I broke the gdbserver build on x86-64 Windows a little while back.
Previously, I could not build this configuration, but today I found
out that if I configure with:

    --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32

using the Fedora 34 tools, it will in fact build.  I'm not certain,
but maybe the gnulib update helped with this.

This patch fixes the build.  I'm checking it in.

8228833924 Fix x86_64 mingw build
PR build/27807 points out that my recent changes to the Windows port
missed a spot in win32-i386-low.cc -- a call to
win32_Wow64GetThreadContext remained, causing link errors in
gdbserver.  This happened because I tested an i686 build, but this
code is only used on an x86_64 build.

This patch fixes the bug.  I am checking it in.

013707794a Enable hardware breakpoints for gdbserver on Windows
When trying to use hardware breakpoints with gdbserver you get this error:

(gdb) hbreak main
Hardware assisted breakpoint 2 at 0x40162d: file gdb-9493.c, line 5.
(gdb) c
Continuing.
Warning:
Cannot insert hardware breakpoint 2.
Could not insert hardware breakpoints:
You may have requested too many hardware breakpoints/watchpoints.

It turns out the respective types just needed to be added to the
appropriate callback functions, because x86_dr_(insert|remove)_watchpoint
already handles them.

	* Makefile.in: Rename source files from .c to .cc.
	* %.c: Rename to %.cc.
	* configure.ac: Rename server.c to server.cc.
	* configure: Re-generate.
