  Log:
  Change semantics of socket close and detach.  Add a new protocol switch
  function, pru_close, to notify protocols that the file descriptor or
  other consumer of a socket is closing the socket.  pru_abort is now a
  notification of close also, and no longer detaches.  pru_detach is no
  longer used to notify of close, and will be called during socket
  tear-down by sofree() when all references to a socket evaporate after
  an earlier call to abort or close the socket.  This means detach is now
  an unconditional teardown of a socket, whereas previously sockets could
  persist after detach of the protocol retained a reference.
  
  This faciliates sharing mutexes between layers of the network stack as
  the mutex is required during the checking and removal of references at
  the head of sofree().  With this change, pru_detach can now assume that
  the mutex will no longer be required by the socket layer after
  completion, whereas before this was not necessarily true.
