Reverse dynamic port assignment

[JayGoldberg]

Use HTTP GET to get the reverse port we should assign on the remote end, in case we want the conducting server to orchestrate port assignments from multiple reverse SSH clients.

Format of file on server:

host=clientname,48859

Where the second number is the port that the client should assign as a remote port connecting to local SSH port (probably 22).

This is becoming more important to me as I have at least a dozen reverse tunnels connected to my host and need to make sure there are no reverse port collisions.

scp may be another way to exchange such data (using a text file).
