Comment:

 I implemented it, with some virtual functions to aid future optimisations
 and some of convenience default implementations of them.

 Most of it are comments, so hopefully this will be trivial.

 I think the ACLs should go to separate library. We could separate the DNS
 based checks to some libdnsacl and have the „generic“ part in libacl, but
 we probably don't want to worry about it yet.

 No changelog is provided, as this code is not used anywhere.
