Initial "opaque SSL" framework. If an application defines

OPENSSL_NO_SSL_INTERN all ssl related structures are opaque
and internals cannot be directly accessed. Many applications
will need some modification to support this and most likely some
additional functions added to OpenSSL.

The advantage of this option is that any application supporting
it will still be binary compatible if SSL structures change.
