* clutter/clutter-actor.c (clutter_actor_destroy): Bail out
	if clutter_actor_destroy() was called on the stage: the stage
	is not for the user to destroy.

	* clutter/x11/clutter-backend-x11.c:
	* clutter/eglnative/clutter-backend-egl.c:
	* clutter/sdl/clutter-backend-sdl.c:
	* clutter/osx/clutter-backend-osx.c: Unset the top-level private
	flag on the stage when disposing it, so the backends can safely
	call clutter_actor_destroy().

	* clutter/clutter-private.h: Tweak the private flags accessors,
	to avoid the typecheck.
