    Make gtk_widget_get_state_flags() avoid propagating the focused flag down the hierarchy
    
    There is only one widget supposed to have the focused flag at a given time,
    so avoid propagating the state down the hierarchy, the focused flag is now
    also set in _gtk_widget_set_has_focus().
