Comment:

 The methods have been made `const`, but `hasRecordInAuthoritySection()`
 can't yet be removed as it does a `RRType` match only whereas
 `Message::hasRRset()` compare other fields as well.

 `hasRecordInAuthoritySection()` is old resolver code and it remains to be
 checked if testing `RRType` only in this codepath is correct code in the
 first place. I'll create a separate ticket for this.

 Up for review.
