[mutter] wayland: Add 'MetaWaylandPopupSurface' bridge between popup and surface

commit 229a143eac5e16c3a0962c58fbb8878b91bafecc
Author: Jonas Ådahl <jadahl gmail com>
Date:   Thu Jan 21 17:01:08 2016 +0800

    wayland: Add 'MetaWaylandPopupSurface' bridge between popup and surface
    
    Add a bridge between the MetaWaylandPopup object and the corresponding
    popup surface role. This bridge replaces communicating dismissed and
    unmapped popup events.
