Security Fixes

     * Duplicate EDNS COOKIE options in a response could trigger an
       assertion failure. This flaw is disclosed in CVE-2016-2088. [RT
       #41809]
     * The resolver could abort with an assertion failure due to improper
       DNAME handling when parsing fetch reply messages. This flaw is
       disclosed in CVE-2016-1286. [RT #41753]
     * Malformed control messages can trigger assertions in named and
       rndc. This flaw is disclosed in CVE-2016-1285. [RT #41666]
     * Certain errors that could be encountered when printing out or
       logging an OPT record containing a CLIENT-SUBNET option could be

       disclosed in CVE-2015-8705. [RT #41397]
     * Specific APL data could trigger an INSIST. This flaw is disclosed
       in CVE-2015-8704. [RT #41396]

       disclosed in CVE-2015-8461. [RT#40945]
     * Insufficient testing when parsing a message allowed records with an
       incorrect class to be be accepted, triggering a REQUIRE failure
