 This is created as a subtask of #505. The purpose here is to correctly
 identify a DNAME and return it from the MemoryZone (eg. return the RRset
 of correct type even when we get into a place with DNAME, but return the
 DNAME if we want to go deeper than there).

 Syntetizing a CNAME will be done as part of #505.

 RFC 2672 mandates that we check data there's nothing under the domain name
 with DNAME, but let's leave it out for now.

 I'm giving it estimate of 3, as it seems to be the „bigger half“ of the
 original task, which was 5.
