* allow ptr queries for cloaked domains
* multi ips per PTR returned + cleanup
* some string tidy up
* enable config file switch
* add cloaked ptr test
* enable cloak ptrs in test scenario
* fix reverse ipv6 ptr lookup
* added ipv6 cloaked ptr test
We now enforce the fact that a query always include a question.
It holds true for all practical use cases of dnscrypt-proxy.
This avoids quite a lot of redundant code in plugins, and is faster.

Previously cache_min_ttl was used. But one can certainly set
cache_min_ttl to 0, but still ensure synthetic values have ttl.
Hence new config file options.
(at least until the TTL expires)
So, if www.google.com is cloaked, and forcesafesearch returns a A
record but no AAAA, return the cloaked A record for A queries, but
don't return the actual AAAA record for AAAA queries: return a
synthetic empty response instead.
