    demux: re-org reading then processing a packet
    
    Replace the handle_packet_cb() callback with the low-level event
    handler process_iface_packet() shared by both TCP and UDP.
    
      s = read(iface, packet)
      switch (s)
        ABORT: close(ifcase) as IKETCP barfed before state was created
        OK: pass packet onto demux and then state
            but don't trust IFACE after call as delete_state()
    	may have been called
        IGNORE: /* try again */
