 Changes between 1.0.1 and 1.1.0  [xx XXX xxxx]



  *) New function SSL_certs_clear() to delete all references to certificates

     from an SSL structure. Before this once a certificate had been added

     it couldn't be removed.

     [Steve Henson]



  *) Initial SSL tracing code. This parses out SSL/TLS records using the

     message callback and prints the results. Needs compile time option

     "enable-ssl-trace". New options to s_client and s_server to enable
