Subject: [PATCH] ssl/s23_clnt.c: set TLS version to 0 in msg_callback for
 record messages

In some cases, the msg_callback was invoked on the record protocol
messages without setting the version to zero.
This confuses the applications which then misinterpret the record's
content.
Eg. the record layer ContentType value 22 (handshake) gets mistakenly
interpreted as HandshakeType value 22 (certificate_status).

This was fixed in 1.1 and above by the version negotiation rewrite
