    menu: Deactivate the menu if the GdkWindow is withdrawn
    
    If the display server or GDK hides the window - fire the "deactivate" signal
    to ensure that the internal state is consistent.
    
    This patch also ensures that the "deactivate" signal will not be fired for a
    menu that is not active.
