    gtk3: implement native context menus
    
    This reuses lots of the unity machinery which is similar
    to the mac concept of a single toplevel menubar.
    
    So to drive popup menus, part of this is a rework that does away with the idea
    that the "menubar" is the controller of the hierarchy, and instead the top
    element becomes the controller
