Log:
  Handle SIGIO for listening sockets
  
  r319722 separated struct socket and parts of the socket I/O path into
  listening-socket-specific and dataflow-socket-specific pieces.  Listening
  socket connection notifications are now handled by solisten_wakeup() instead
  of sowakeup(), but solisten_wakeup() does not currently post SIGIO to the
  owning process.
