Import nsd-4.1.26

29 November 2018: Wouter
        - Tag for 4.1.26rc1.

27 November 2018: Wouter
        - Fix parsezone failure in 4194 fix.

26 November 2018: Wouter
        - Fix to not set GLOB_NOSORT so the nsd.conf include: files are
          sorted and in a predictable order.
        - Added nsd-control changezone.  nsd-control changezone name pattern
          allows the change of a zone pattern option without downtime for
          the zone, in one operation.
        - Fix #3433: document that reconfig does not change per-zone stats.

20 November 2018: Wouter
        - Fix #4205: enable-recvmmsg in mixed IPv4/IPv6 environment fails.
          This sets the msg_hdr.msg_namelen correctly after receipt.

19 November 2018: Wouter
        - Support SO_REUSEPORT_LB in FreeBSD 12 with the reuseport: yes
          option in nsd.conf.
        - Fix #4202: nsd-control delzone incorrect exit code on error.
        - Tab style fix to use tab for 8 spaces, from Xiaobo Liu.

25 October 2018: Wouter
        - Adjust dnstap socket path for chroot.

22 October 2018: Wouter
        - Fix #4194: Zone file parser derailed by non-FQDN names in RHS of
          DNSSEC RRs.
        - Fix some more, neater code and checks for domain length limit.
        - check that the dnstap socket file can be opened and exists, print
          error if not.

4 October 2018: Wouter
        - dnstap work, the dnstap.proto is a copy of the file from Unbound,
          also dnstap.m4 configure include file.
        - dnstap collector: free eventbase and memclean nicer.
        - dnstap collector: send data and read it in collector.
        - dnstap/dnstap.c and .h from Unbound's contribution from
          Farsight Security, added to then adapt it for dnstap logging in NSD.
        - dnstap.c with auth query and auth response, and called from
          the collector.
        - dnstap work, config nsd.conf parse.
        - dnstap example config.

25 September 2018: Wouter
        - NSD 4.1.25 released, trunk has 4.1.26 in development.

18 September 2018: Wouter
        - tag for NSD 4.1.25rc1.

17 September 2018: Wouter
        - Fix #4156: Fix systemd service manager state change notification

14 September 2018: Wouter
        - Remove unused if clause during server service startup.

13 September 2018: Wouter
        - Fix typo in clang analysis test.
        - Annotate exit functions with noreturn.
        - nsd-control prints neater errors for file failures.

12 September 2018: Wouter
        - clang analysis test.

11 September 2018: Wouter
        - Fix to combine the same error function into one, from Xiaobo Liu.
        - Fix initialisation in remote.c.
        - please clang analyzer and fix parse of IPSECKEY with bad gateway.
        - Fix unit test code for clang analyzer.
        - Fix nsd-checkconf fail on bad zone name.

10 September 2018: Wouter
        - Fix coding style in nsd.c

7 September 2018: Wouter
        - append_trailing_slash has one implementation and is not repeated
          differently.

4 September 2018: Wouter
        - Fix codingstyle in nsd-checkconf.c in patch from Sharp Liu.
