- 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
