- at_ifawithnet(), which acquires an locks it needs and returns an at_ifaddr reference. - at_ifawithnet_locked(), which relies on the caller locking at_ifaddr_list, and returns a pointer rather than a reference. Update various consumers to prefer one or the other, including ether and fddi output, to properly release at_ifaddr references. Rework at_control() to manage locking and references in a manner identical to in_control(). MFC after: 6 weeks
