    tcp: Allow pure asynchronized pru_send
    
    - net.inet.tcp.sosnd_async is added to allow pure asynchronized pru_send.
      It is default to off currently.
    - To prevent soclose() and soshutdown() from interfering TCP processing on
      the loopback interface, so_pru_sync() is added, which will make sure
      that so_pru_disconnect() and so_pru_shutdown() run only after all of the
      previous sent packets had been requeued to netisr (the semantics of the
      original half asynchronized pru_send).
