CVE-2014-3566

This will requires fixes in openssl, gnutls and nss. Firefox also needs a fix since it uses a local nss copy. (There are additional Firefox issues, so I'll file a separate bug).

We don't need to update gnutls; disabling SSL3 is too intrusive for UCS 3.2 and all TLS/SSL clients (besides web browsers, which perform a special downgrade path) support TLS and will use that during the SSL/TLS handshake.
