Log Message:
Unbound 1.5.2

Features:
* local-zone: example.com inform makes unbound log a message with
  client IP for queries in that zone. Eg. for finding infected hosts.
* patch from Stephane Lapie that adds to the python API, that
  exposes struct delegpt, and adds the find_delegation function.
* Updated contrib warmup.cmd/sh to support two modes - load from
  pre-defined list of domains or (with filename as argument) load from
  user-specified list of domains, and updated contrib
  unbound_cache.sh/cmd to support loading/save/reload cache to/from
  default path or (with secondary argument) arbitrary path/filename
* patch for remote control over local sockets. Use control-interface:
  /path/sock and control-use-cert: no.
* unbound-checkconf -f prints chroot with pidfile path.
* infra-cache-min-rtt patch from Florian Riehm, for expected long
  uplink roundtrip times.
