This change adds support for the new _NET_WM_FULLSCREEN_MONITORS

Browse Source 
property and client message.  This allows client applications to request
 	that a fullscreen window cover more than one monitor.
 	* src/include/boxes.h:
	* src/core/boxes.c: Add meta_rectangle_union
 	* src/core/window-private.h:
	* src/core/window.c:
 	(meta_window_new_with_attrs, meta_window_free, set_net_wm_state,
 	meta_window_update_fullscreen_monitors, meta_window_client_message): Add
 	MetaWindow property to store fullscreen monitors field, update
 	_NET_WM_FULLSCREEN_MONITORS property on windows, and handle client
 	message.
 	* src/core/atomnames.h: Add _NET_WM_FULLSCREEN_MONITORS atom.
 	* src/core/constraints.c (setup_constraint_info): If
 	_NET_WM_FULLSCREEN_MONITORS is interesting, use the data stored in
 	MetaWindow::fullscreen_monitors to determine the fullscreen area instead
 	of the basic xinerama_info area.
