	Make it possible to determine if a key event is for a
	modifier key:

 	* gdk/x11/gdkprivate-x11.h:
	* gdk/x11/gdkkeys-x11.c (_gdk_keymap_key_is_modifier):
	New function to determine if a keycode is mapped to a modifier.
	(get_xkb): Get the modmap.

	* gdk/x11/gdkevents-x11.c (translate_key_event): Set the
	is_modifier bit by calling _gdk_keymap_key_is_modifier().

	* gdk/gdkevents.h (struct _GdkEventKey): Add an is_modifier
	bit.
