[RFC 0/2] Restore previously selected frame when switching thread

[Andrew Burgess]

The interesting part of this series is patch #2, where I change GDB so
that the current frame is tracked per thread, and GDB will restore the
current frame when switching back to a previously visited thread.

This is RFC as there were some aspects of the patch that I wasn't 100%
sure on, these are all described in the patch #2 commit message.

All feedback and thoughts welcome.

Thanks,
Andrew
