Turn gdbpy_ref into a template

This turns gdbpy_ref into a template class, so that it can be used to
wrap subclasses of PyObject.  The default argument remains PyObject;
and this necessitated renaming uses of "gdbpy_ref" to "gdbpy_ref<>".

	* python/py-ref.h (gdbpy_ref_policy): Now a template.

	used.

	python/py-cmd.c, python/py-continueevent.c, python/py-event.c,
	python/py-exitedevent.c, python/py-finishbreakpoint.c,
	python/py-framefilter.c, python/py-function.c,
	python/py-inferior.c, python/py-infevents.c,
