  Do not shadow tm on line 236. (NLnetLabs#1243)
  - Fix hash calculation for cachedb to ignore case. Previously, cached   records there were only relevant for same case queries (if not   already in Unbound's internal cache).
  Changelog entry for NLnetLabs#1241: - Merge NLnetLabs#1241: Fix infra-keep-probing for low infra-cache-max-rtt   values.
  - The maximum value of a probe rto was not aligned with the   (configurable) infra-cache-max-rtt value. That could result in   infra-keep-probing not working if an infra-cache-max-rtt value was chosen   that was below 12000 ms. This fix still uses a default value of 12000   ms for the probe but caps it to the infra-cache-max-rtt if that is   lower.
  - Fix static analysis report about unhandled EOF on error conditions   when reading anchor key files.
  - Consider reconfigurations when calculating the still_useful_timeout   for servers in the infrastructure cache.
  - Fix NLnetLabs#986: Resolving sas.com with dnssec-validation fails though   signed delegations seem to be (mostly) correct.
  - Make the default value of module-config "validator iterator"   regardless of compilation options. --enable-subnet would implicitly   change the value to enable the subnetcache module by default in the   past.
