     Add support for tun(4) forwarding over OpenSSH, based on an idea and
     initial channel code bits by markus@. This is a simple and easy way to
     use OpenSSH for ad hoc virtual private network connections, e.g.
     administrative tunnels or secure wireless access. It's based on a new
     ssh channel and works similar to the existing TCP forwarding support,
     except that it depends on the tun(4) network interface on both ends of
     the connection for layer 2 or layer 3 tunneling. This diff also adds
     support for LocalCommand in the ssh(1) client.

     ok djm@, markus@, jmc@ (manpages), tested and discussed with others

     implement support for X11 and agent forwarding over multiplex slave
     connections. Because of protocol limitations, the slave connections inherit
     the master's DISPLAY and SSH_AUTH_SOCK rather than distinctly forwarding
     their own.
