Preserve stacking order across restarts.

	Preserve stacking order across restarts.

	* src/display.c (meta_display_unmanage_windows_for_screen):
	unmap windows in stacking order so that stacking is preserved upon
	shutdown

	* src/display.[ch] (meta_display_stack_cmp):
	* src/session.c (stack_cmp, save_state):
	rename stack_cmp() -> meta_display_stack_cmp() and move it to a
	different function so that it can be used in both
	session.c:save_state() and
	meta_display_unmanage_windows_for_screen()
