Backport support for fs_base/gs_base and $_siginfo from GDB master.

Bring in two patchsets committed to GDB master along with a few other commits
those patchsets depend on.
- Add support for examining $_siginfo.  When a thread has valid signal
  information, report the current information in a $_siginfo variable.
  For live processes the values are extracted via the PT_LWPINFO ptrace
  request.  The values are also extracted from process core dumps that
  include NT_LWPINFO notes (currently only present in FreeBSD 12-current).
- Add support for the $fs_base and $gs_base registers on amd64.  This only
  works for live processes via the PT_{GET,SET}{FS,GS}BASE ptrace requests.
  FreeBSD currently does not store these values in core dumps, so they are
  not available from core dumps.
