Security Fixes

     * A coding error in the nxdomain-redirect feature could lead to an
       assertion failure if the redirection namespace was served from a
       local authoritative data source such as a local zone or a DLZ
       instead of via recursive lookup. This flaw is disclosed in
       CVE-2016-9778. [RT #43837]
     * Named could mishandle authority sections that were missing RRSIGs
       triggering an assertion failure. This flaw is disclosed in
       CVE-2016-9444. [RT # 43632]
     * Named mishandled some responses where covering RRSIG records are
       returned without the requested data resulting in a assertion
       failure. This flaw is disclosed in CVE-2016-9147. [RT #43548]
     * Named incorrectly tried to cache TKEY records which could trigger a
       assertion failure when there was a class mismatch. This flaw is
       disclosed in CVE-2016-9131. [RT #43522]
     * It was possible to trigger assertions when processing a response.
       This flaw is disclosed in CVE-2016-8864. [RT #43465]
