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).
