OpenSSL compliance with Linux distributions

[Jakob Bohm]

The key thing to do is to make those client applications not request the 
ssl23-method from OpenSSL 0.9.x .
ssl23 explicitly requests this backward-compatibility feature while 
OpenSSL 3.x.x apparently deleted the
ability to respond to this "historic" TLS hello format, which is also 
sent by some not-that-old web browsers.
