FTP tunnelling patch

[A. Uk / dataway GmbH]

Hello everyone,

I have made a very crude patch against OpenSSL-3.8p1 for secure FTP
forwarding. It intercepts the server's "227 Entering Passive Mode"
message and opens a forwarding port. Not the best of code, but it
works for the one application where I need it.

Let me know if this is at all something that could go into the main
codebase; if so I will polish it up.

regards,
anthony
