	* gtk/gtkrc.[ch]: added new scanner token "unbind" which gets
	rid of a key binding (in fact, it only lets it appear unbound).

	* gtk/gtkbindings.[ch] (struct GtkBindingEntry): added
	"guint marks_unbound : 1"

	(gtk_binding_entry_skip): new API which marks the entry as unbound.

	Changed code so it returns FALSE when "marks_unbound == TRUE" is
	encountered while activating bindings, effectively letting the
	binding appear unbound (regardless of still existing bindings in
	lower binding priority levels). Fixes bug #358329.

	(gtk_binding_entry_add)
	(gtk_binding_entry_clear)
	(gtk_binding_entry_add_signall)
	(gtk_binding_parse_binding): deprected these functions.

	(_gtk_binding_parse_binding)
	(_gtk_binding_entry_add_signall): new internal API.

	* gtk/gtk.symbols: changed accordingly.
