    Add map/unmap to GtkActionBar
    
    The recursion in map needs to follow the actual physical
    widget tree, otherwise we violate invariants. The generic
    container map implementation uses gtk_container_forall to
    operate on the children, and thus is not suitable for
    containers where the children are inside some internal
    container.
