      openssl s_client has a new '-servername' option.
 
-     openssl s_server has new options '-servername', '-cert2', and '-key2';
-     this allows testing the HostName extension for a specific single
-     host name ('-cert' and '-key' remain fallbacks for handshakes without
-     HostName negotiation).
