    Fix accounting of frozen with maximize/unmaximize
    
    The beginning maximization/unmaximization don't go through
    start_effect_simple(), so we need to freeze the window
    separately.
    
    Change MutterWindow.freeze_count to a signed integer for
    consistency with other counts, and so the logic for
    checking for errors works properly.
