socket: disallow CBC cipher modes
This is related to CVE-2014-3566 a.k.a. POODLE. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566 POODLE is specific to CBC cipher modes in SSLv3. Because there is no way to prevent SSLv3 fallback on a system with an unpatched version of OpenSSL, users of such systems can only be protected by disallowing CBC modes. The default cipher-mode specification in our code has been changed accordingly. Users can still set their own cipher modes if they wish. To support them, the ssl-authz.t test script provides an example of how to combine the CBC exclusion with other criteria in a script.
