commit 98a0f9660d374f58f79ee0efcc8c1672a805e8e8
Author: Dr. Stephen Henson <steve@openssl.org>

Unauthenticated DH client certificate fix.
    
    Fix to prevent use of DH client certificates without sending
    certificate verify message.
    
    If we've used a client certificate to generate the premaster secret
    ssl3_get_client_key_exchange returns 2 and ssl3_get_cert_verify is
    never called.
    
    We can only skip the certificate verify message in
    ssl3_get_cert_verify if the client didn't send a certificate.
    
    Thanks to Karthikeyan Bhargavan for reporting this issue.
