     Add support for Unix domain socket forwarding.  A remote TCP port
     may be forwarded to a local Unix domain socket and vice versa or
     both ends may be a Unix domain socket.  This is a reimplementation
     of the streamlocal patches by William Ahern from:
         http://www.25thandclement.com/~william/projects/streamlocal.html
