Apply patch by Vytautas Liuolia for changing the startup notification id

2007-03-13  Emmanuele Bassi  <ebassi@gnome.org>

	Apply patch by Vytautas Liuolia for changing the startup
	notification id on a window in the X11 backend. (#347375)

	* gdk/gdk.h:
	* gdk/gdkx.h:
	* gdk/x11/gdkdisplay-x11.c: Add gdk_notify_startup_complete_wit_id()
	and gdk_x11_display_get_startup_notification_id().

	* gdk/gdkwindow.h:
	* gdk/x11/gdkwindow-x11.c: Add gdk_window_set_startup_id().

	* gtk/gtkwindow.h:
	* gtk/gtkwindow.c: Add gtk_window_set_startup_id(), used to
	change the startup notification id.
	
	(gtk_window_class_init), (gtk_window_init),
	(gtk_window_set_property): Add write-only "startup-id" property
	to GtkWindow.

	(gtk_window_realize): Set the startup notification id
	on a GtkWindow if it's valid.

	(gtk_window_map): If we have another valid startup notification
	id then finish the notification process.
