Upgrade to GDB 8.0.

- Commit b5430a3ced fixes parsing of 32-bit MIPS process cores.
- kgdb has been ported to 8.0 including renaming the new OSABI constant,
  using gdb_bfd_openr, new return type of ldirname, and solib_add
  changed.
- GDB 8.0 requires C++11, however the port is marked as requiring C++14
  as a workaround for bugs in clang 10.3.
- patch-armfbsd is updated for the new OSABI constant names (a.out was
  removed in 8.0) and new filename convention (arm-fbsd-*)
- patch-gdb-amd64-bsd-nat.c (renamed from patch-gdbamd64-bsd-nat.c) is
  simplified to just store the r_flags value before collecting registers
  from the register cache rather than a full copy of the entire register
  set.
- patch-gdb-corelow.c has been removed.  It isn't really correct and if
  arm cores still cause core dumps the error is in arm-fbsd-tdep.c.
- patch-gdb-i386-fbsd-nat.c renamed to account for rename of patched
  file.
- patch-gdb-x86bsd-nat.c has been removed.  The file was renamed, but the
  stock file also compiled fine for me on i386.

Update gdb to 7.10

* Removing patches from the port already committed in upstream
* Adopting the new OPTION dependent targets (like do-install-PYTHON-on:)
* Enable support for 64-bit targets on 32-bit systems (e.g. allow the i386
  gdb to debug an amd64 binary).
* Now supports fork and exec tracing.

Update to 7.9.
- Move changes that have been adopted upstream after 7.9 into extra patches
  named after the commit to GDB's master branch.  This includes previous
  patches such as the signal trampoline detection fixes and XSAVE support
  as well as well as new fixes such as fixing 'gcore' to not require procfs.
- The tui-io.c patch previously needed with new readline has been accepted
  upstream.
- The remaining patches have been updated to apply cleanly.
- The threads target has been fixed to actually pass register requests for
  LWP-backed threads down to the ptrace backends without detouring via
  libthread_db which actually fixes AVX with threads.

- Add support for XSAVE on amd64 and i386 using the recently added
  PT_GETXSTATE_INFO and XSTATE core dump sections.
- Use kern.proc.sigtramp on i386 to fix unwinding across signal
  frames.
- Change the amd64 FreeBSD ABI to return an i386 target description
  when debugging a 32-bit process.  This allows XSAVE debugging to
  work for an i386 binary on amd64.
- Rework thread patches to pull all threads-related patches out of
  the main port patches and into a single optional patch.
- Adjust the thread patches so that fbsd-threads.c passes register
  requests for LWPs down to the native target instead of calling
  ptrace directly.  This allows XSAVE to work with threads without
  any other changes.  The x86 nat.c files now pass LWP IDs to
  ptrace register operations (other platforms already did this).
  The supply/collect regset stubs are now only needed to support
  userland threads for libkse.

GDB is a source-level debugger for Ada, C, C++, Objective-C, Pascal and
many other languages.  GDB can target (i.e., debug programs running on)
more than a dozen different processor architectures, and GDB itself can
run on most popular GNU/Linux, Unix and Microsoft Windows variants.

This version of gdb has been modified by jhb@ to recognize freebsd threads
