upstream commit
Expose devices allocated for tun/tap forwarding.
At the client, the device may be obtained from a new %T expansion
for LocalCommand.
At the server, the allocated devices will be listed in a
SSH_TUNNEL variable exposed to the environment of any user sessions
started after the tunnel forwarding was established.
