Merge from clutter.git/master

	* clutter/glx/clutter-event-glx.c:
	* clutter/glx/clutter-stage-glx.c: Implement the _NET_WM_PING
	protocol handling on the main stage window.

	* clutter/clutter-stage.h:
	* clutter/clutter-stage.c:
	* clutter/clutter-main.c: Handle CLUTTER_DELETE events internally,
	by calling clutter_main_quit(), and remove the ::delete-event
	signal from ClutterStage; clean up the signal emission sequence
	for the events: emit the ::event signal before emitting any signal
	and the ::event-after signal after the signal has been emitted; move
	the signal emission calls inside ClutterStage so we can call
	g_signal_emit() instead of g_signal_emit_by_name(), thus sparing us
	a lookup for each event.

	* examples/test.c: Remove ::delete-event signal handling.
