This allows adding a GActionGroup with a given name at an arbitrary point in the widget tree. This patch also adds an internal _get_action_muxer() API. Calling this will create a GActionMuxer associated with the widget. The parent of the muxer will be the muxer of the widget's conceptual parent. For non-menus, that is the normal parent. For menus, it is the attach widget. In this way, we end up with a hierarchy of GActionMuxer that largely reflects the hierarchy of GtkWidget, but only in places that the action context has been requested. These muxers are the ones on which the inserted actions groups are installed. A following patch will add a user of this API.
