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.
