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.

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.

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.

This adds a decr_pc_after_break member to win32_target_ops and updates
the two Windows targets to set it.
Note that I can't test the win32-arm-low.c change.

This changes win32-low.c to implement the read_pc and write_pc

This renames win32_thread_info to windows_thread_info in gdbserver.
This renaming helps make it possible to share some code between gdb
and gdbserver.

For the same reasons outlined in the previous patch, this patch renames
gdbserver source files to .cc.
I have moved the "-x c++" switch to only those rules that require it.
gdbserver/ChangeLog:
* Makefile.in: Rename source files from .c to .cc.
* %.c: Rename to %.cc.
* configure.ac: Rename server.c to server.cc.
* configure: Re-generate.
