Mark J. Cox 413c4f45ed Updates to the new SSL compression code
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]

Fix so that the version number in the master secret, when passed
     via RSA, checks that if TLS was proposed, but we roll back to SSLv3
     (because the server will not accept higher), that the version number
     is 0x03,0x01, not 0x03,0x00
