Centralize workaround for Python 2.6's Py_DECREF.

Browse Source 
Wrap/redefine Py_DECREF ourselves, avoiding the need for uses to care
about extra braces due to the fact that Python only started wrapping Py_DECREF
in 'do {} while (0)' after 2.6.

2013-05-21  Pedro Alves  <palves@redhat.com>

	* python/py-utils.c (py_decref): Remove extra braces.
	(gdb_pymodule_addobject): Remove extra braces.
	* python-internal.h (gdb_Py_DECREF): New static inline function.
	(Py_DECREF): Redefine as calling gdb_Py_DECREF.
