[PATCH 0/3] Python/TUI Window Creation / Destruction Fixes

[Andrew Burgess <aburgess@redhat.com>]

Patch #1 started with an observation that the behaviour of
gdb.register_window_type doesn't appear to exactly match up with the
documentation.

While fixing this I observed that the destruction of Python window
factory callbacks (as used by gdb.register_window_type) is
inconsistent, and that GDB knowingly leaks some memory in this area
too.  Patches #2 and #3 fix this and make the destruction behaviour
consistent.

All feedback welcome.

Thanks,
Andrew
