Remove APIs: ges_track_element_set_locked ges_track_element_is_locked Those APIs where really not nice to use and were causing more issues than solving them. If 2 time related properties of TimelineElement must be different, then those element can *not* have the same parent. Plus, with the new ges_container_group () API, we will recreate 1 GESClip containing the proper GESTimelineElements if it is the thing to do.
