	Fix bug 143333, support for update counter spec, and 109362,
	schedule compensation events when events are ignored.

	* src/display.c (meta_display_open): Add _NET_WM_SYNC_REQUEST and
	_NET_WM_SYNC_REQUEST_COUNTER atoms. Remove the old
	METACITY_SYNC_COUNTER stuff.
	(meta_display_begin_op): Setup the sync counter

	* src/xprops.c, src/xprops.h, src/window-props.c, src/display.h:
	Add new atoms.

	* src/window.c (send_sync_request): new function.
	(meta_window_move_resize_internal): send a sync request before
	resizing.
	(check_move_resize_frequence): Rework logic to also check the SYNC
	case. If an event is ignored return the remaining time.
	(update_resize_timeout): Timeout that gets called when a
	compensation event is scheduled.
	(uddate_resize): schedule compensation events when an event is
	ignored.
	(meta_window_handle_mouse_grap_op_event): When an alarm is
	received and sync was turned off, turn it back on.

	* src/window.h (struct MetaWindow)  Add some variables
