    wayland: Add a hack to give focus to Wayland clients on mouse clicks
    
    The rest of the Mutter code doesn't really know about surfaces from
    Wayland clients so nothing will give them keyboard focus. This adds a
    temporary hack to give them keyboard focus whenever a button press
    event is sent to a surface with no corresponding X id.
