Hi,

This release fixes a couple of minor bugs and adds IXFR out
functionality. With this functionality NSD can respond to IXFR queries
and serve IXFR transfers downstream.

It is default disabled, that means it does not store IXFR contents for
zones by default. The response on the wire is different, also with IXFR
disabled, because it is now supported, and thus also for those zones a
reply is served, that no differential data is available.

4.5.0
================
FEATURES:
- Merge PR #209: IXFR out
  This adds IXFR out functionality to NSD. NSD can copy IXFRs from
  upstream to downstream clients, or create IXFRs from zonefiles.
  The options store-ixfr: yes and create-ixfr: yes can be used to
  turn this on. Default is turned off. The options ixfr-number and
  ixfr-size can be used to tune the number of IXFR transfers and
  total data size stored. This is configured per zone, the IXFRs
  are served to the hosts that are allowed to perform zone transfers.
  And if TSIG is configured, signed with the same key. The content
  is stored to file if a zonefile is configured for the zone, in
  the zonefile.ixfr and zonefile.ixfr.2, .. files. They contain
  readable text format. The number of IXFRs is num.rixfr in
  statistics output, also per zone if per zone statistics are enabled.
  If offline, nsd-checkzone -i can create ixfr files.
  NSD already supports requesting IXFRs, this addition allows NSD
  to serve IXFR transfers to clients.
  NSD stops responding with NOTIMPL to IXFR requests, also for zones
  that do not have IXFR enabled. The clients gets a full zone reply
  or a status reply if the serial is up to date.

- Fix code analyzer zero divide warning.
- Fix code analyzer large value with assertion.
- Fix another code analyzer zero divide warning.
- Fix code analyzer warning about uninitialized temp storage in loop.
