	Add support for _NET_MOVERESIZE_WINDOW.  #344521.

	* src/display.c (handle_net_moveresize_window, event_callback):
	Remove handle_net_moveresize_window() and the call to it; this
	code was highly buggy, though to be fair it was never tested and
	had simply been put into the code in commented out form.

	* src/screen.c (set_supported_hint):
	add atom_net_moveresize_window

	* src/window.[ch]:
	(meta_window_configure_request, meta_window_move_resize_request):
	Split out the moving/resize part of the configure request and put
	it into meta_window_move_resize_request

	(meta_window_client_message):
	check for NET_MOVERESIZE_WINDOW messages and call
	meta_window_move_resize_request() with the appropriate parameters
	to handle them

	(meta_window_move_resize_internal):
	fix some of the big comment at this function -- it wasn't quite
	right, use the passed in gravity instead of
	window->size_hints.win_gravity when calling adjust_for_gravity()
	to make sure the correct adjustments are used.

	(meta_window_get_gravity_position,
	 meta_window_get_geometry, meta_window_move_resize_request):
	add a gravity parameter to meta_window_get_gravity_position and
	have it use that gravity instead of window->size_hints.win_gravity
