  Modified files:
    sys/fs/fifofs        fifo_vnops.c 
    sys/kern             uipc_socket.c 
    sys/sys              socket.h 
  Log:
  Add MSG_NBIO flag option to soreceive() and sosend() that causes
  them to behave the same as if the SS_NBIO socket flag had been set
  for this call.  The SS_NBIO flag for ordinary sockets is set by
  fcntl(fd, F_SETFL, O_NONBLOCK).
  
  Pass the MSG_NBIO flag to the soreceive() and sosend() calls in
  fifo_read() and fifo_write() instead of frobbing the SS_NBIO flag
  on the underlying socket for each I/O operation.  The O_NONBLOCK
  flag is a property of the descriptor, and unlike ordinary sockets,
  fifos may be referenced by multiple descriptors.
