Update bind910 to 9.10.4 (BIND 9.10.4).

PKG_OPTIONS change:

    * Remove rrl which is always enabled.
    * Add fetchlimit, geoip, pkcs11, sit and tuning.

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
      mishandled, resulting in an assertion failure. This flaw is
      disclosed in CVE-2015-8705. [RT #41397]
    * Specific APL data could trigger an INSIST. This flaw is disclosed
      in CVE-2015-8704. [RT #41396]
    * Incorrect reference counting could result in an INSIST failure if a
      socket error occurred while performing a lookup. This flaw is
      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
      when those records were subsequently cached. This flaw is disclosed
      in CVE-2015-8000. [RT #40987]

New Features

    * The following resource record types have been implemented: AVC,
      CSYNC, NINFO, RKEY, SINK, SMIMEA, TA, TALINK.
    * Added a warning for a common misconfiguration involving forwarded
      RFC 1918 and IPv6 ULA (Universal Local Address) zones.
    * Contributed software from Nominum is included in the source at
      contrib/dnsperf-2.1.0.0-1/. It includes dnsperf for measuring the
      performance of authoritative DNS servers, resperf for testing the
      resolution performance of a caching DNS server, resperf-report for
      generating a resperf report in HTML with gnuplot graphs, and
      queryparse to extract DNS queries from pcap capture files. This
      software is not installed by default with BIND.
    * When loading a signed zone, named will now check whether an RRSIG's
      inception time is in the future, and if so, it will regenerate the
      RRSIG immediately. This helps when a system's clock needs to be
      reset backwards.

Feature Changes

    * Updated the compiled-in addresses for H.ROOT-SERVERS.NET and
      L.ROOT-SERVERS.NET.
    * The default preferred glue is now the address type of the transport
      the query was received over.
    * On machines with 2 or more processors (CPU), the default value for
      the number of UDP listeners has been changed to the number of
      detected processors minus one.
    * Zone transfers now use smaller message sizes to improve message
      compression. This results in reduced network usage.
    * named -V output now also includes operating system details.

Porting Changes

    * The Microsoft Windows install tool BINDInstall.exe which requires a
      non-free version of Visual Studio to be built, now uses two files
      (lists of flags and files) created by the Configure perl script
      with all the needed information which were previously compiled in
      the binary. Read win32utils/build.txt for more details. [RT #38915]

Bug Fixes

    * rndc flushtree now works even if there wasn't a cached node at the
      specified name. [RT #41846]
    * Don't emit records with zero TTL unless the records were received
      with a zero TTL. After being returned to waiting clients, the
      answer will be discarded from the cache. [RT #41687]
    * For Windows platforms, the SIT (Source Identity Token) support was
      restored. (It was mistakenly partially replaced in a previous beta
      with new 9.11 COOKIE support.) [RT #41905]
    * When deleting records from a zone database, interior nodes could be
      left empty but not deleted, damaging search performance afterward.
      [RT #40997] [RT #41941]
    * The server could crash due to a use-after-free if a zone transfer
      timed out. [RT #41297]
    * Authoritative servers that were marked as bogus (e.g. blackholed in
      configuration or with invalid addresses) were being queried anyway.
      [RT #41321]
    * Some of the options for GeoIP ACLs, including "areacode",
      "metrocode", and "timezone", were incorrectly documented as "area",
      "metro" and "tz". Both the long and abbreviated versions are now
      accepted.
    * Zones configured to use map format master files can't be used as
      policy zones because RPZ summary data isn't compiled when such
      zones are mapped into memory. This limitation may be fixed in a
      future release, but in the meantime it has been documented, and
      attempting to use such zones in response-policy statements is now a
      configuration error. [RT #38321]
