Tom Tromey b5eba2d8c0 Release the GIL while running a gdb command or expression 
PR python/23615 points out that gdb.execute_gdb_command does not
release the Python GIL.  This means that, while the gdb command is
running, other Python threads do not run.

This patch solves the problem by introducing a new RAII class that can
be used to temporarily release and then re-acquire the GIL, then puts
this into the appropriate places in execute_gdb_command and
gdbpy_parse_and_eval.

This does not include a test case, because after some research I could
not find a way to write one that was not racy.
