  Modified files:
    sys/kern             uipc_socket.c 
  Log:
  Revert sosend() to its behavior from 4.3-Tahoe and before: if
  so_error is set, clear it before returning it.  The behavior
  introduced in 4.3-Reno (to not clear so_error) causes potentially
  transient errors (e.g.  ECONNREFUSED if the other end hasn't opened
  its socket yet) to be permanent on connected datagram sockets that
  are only used for writing.
  
  (soreceive() clears so_error before returning it, as does
  getsockopt(...,SO_ERROR,...).)
