(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.

For those low values of rtt, the probe continuation is fairly nice to have. The code looks nice, expanded with a unit test.

* nlnet/master: (37 commits) - Fix for windows compile create ssl contexts. - Fix NLnetLabs#1251: WSAPoll first argument cannot be NULL. - Fix representation of types GPOS and RESINFO, add rdf type for - Fix 'unbound-control flush_negative' when reporting removed data; reported by David 'eqvinox' Lamparter. Changelog nore for NLnetLabs#1238 and add `--help` description. - Merge NLnetLabs#1238: Prefer SOURCE_DATE_EPOCH over actual time. Add --help output description for the SOURCE_DATE_EPOCH variable.

(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).
