Having completed the conversion of the topology server and
configuration server to use the new server infrastructure,
the following functions become unused, and can be deleted:

   - tipc_createport()
   - port_wakeup_sh()
   - port_dispatcher()
   - port_dispatcher_sigh()
   - tipc_send_buf_fast()
   - tipc_send_buf2port

Additionally, the following variables become orphaned,
and can be deleted:

   - tipc_msg_err_event
   - tipc_named_msg_err_event
   - tipc_conn_shutdown_event
   - tipc_msg_event
   - tipc_named_msg_event
   - tipc_conn_msg_event
   - tipc_continue_event
   - msg_queue_head
   - msg_queue_tail
   - queue_lock

Deletion is done here in a separate commit in order to allow
the actual conversion changes to be more easily viewed.
