Make sure apps have correct info about their coordinates, even on unmap.

	Make sure apps have correct info about their coordinates, even on
	unmap.  Fixes temporary hang with libXt (XtVaSetValues setting x &
	y coordinates).  #399552.

	* src/frame.c (meta_window_destroy_frame): Add a comment noting
	that the current choice causes the need for a ConfigureNotify
	event

	* src/window.c (meta_window_free): Send a configure notify event
	due to our XReparentWindow coordinate choices on withdrawal,
	(unmaximize_window_before_freeing): no need to send a configure
	notify from here since it is always done in meta_window_free new,
	(send_configure_notify): have to special case the coordinates used
	when withdrawing the window
