Comment(by jinmei):

 Replying to [comment:1 zzchen_pku]:
 > It's ready for review now, since MemoryZone hasn't implemented "GLUE OK"
 mode find() yet, additional processing for NS will simply search the whole
 zone for address records.

 Some initial feedback:
  - we should test the case where (some of) the NS name is out of zone.
 please also consider where to reject such case, i.e. within the Query
 class or delegate it to the underlying zone.  The former should be more
 efficient but requires more code.
  - likewise, we should test the case where NS name has a CNAME.
  - shouldn't getAdditional()/findAddrs() be private?
  - getAdditional() can throw because getRdataIterator() or Zone::find()
 can.
