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.
