[gtk+/nth-child: 7/22] API: Change semantics of gtk_container_get_child_path()

    API: Change semantics of gtk_container_get_child_path()
    
    Include the child widget path in the returned path now. This allows
    customizing the path of the current widgets - like adding flags to child
    widgets (and maybe siblings in the future).
