Juliusz Sosinowicz 1f4afe9ccc F-5810: require renegotiation_info on renegotiation ClientHello
The server validated client_verify_data only inside
TLSX_SecureRenegotiation_Parse, which never runs when the renegotiation_info
extension is absent, so a renegotiation ClientHello that omitted it was never
checked. Track a per-handshake renegInfoSeen flag and, after parsing the
renegotiation ClientHello extensions, abort with handshake_failure if the
extension was absent (RFC 5746 3.7). Also reject an SCSV received during
renegotiation (RFC 5746 3.5).
