History
mvs f1bf6f4e82 Use per-sockbuf mutex(9) to protect `so_rcv' buffer of tcp(4) sockets. 
Only unlock soreceive() path, somove() path still locked exclusively. Also
exclusive  socket lock will be taken in the soreceive() path each time
before pru_rcvd() call.

Note, both socket and `sb_mtx' locks are held while SS_CANTRCVMORE
modified, so socket lock is enough to check it in the protocol input
path.
