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.
