This change revamps SSH banner parsing. The previous behavior was both a bit too strict in some regards, and too permissive in other. Specifically, clients are now required to send a line starting with "SSH-" as the first line. This is in line with the RFC, as well with observed behavior. This also prevents the creation of `ssh.log` for non-SSH traffic on port 22. For the server side, we now accept text before the SSH banner. This previously led to a protocol violation but is allowed by the spec. New tests are added to cover these cases.
