        * ospf_apiserver.{c,h}: lists typedef removal cleanup.
          update some list loops to LIST_LOOP. some miscellaneous indent
          fixups.
          (ospf_apiserver_unregister_opaque_type) fix listnode_delete of
          referenced node in loop.
        * ospf_interface.h: lists typedef removal cleanup.
        * ospf_opaque.{c,h}: lists typedef removal cleanup. update some list
          loops to LIST_LOOP. miscellaneous style and indent fixups.
        * ospf_te.{c,h}: ditto
	* ospf_packet.c: lists typedef removal cleanup.
