Comment (by jinmei):

 trac1571 is ready for review.

 This is quite simple, and basically follows what BIND 9 does.
 In fact, BIND 9 generalizes it by introducing the notion of "at
 parent" type of RRs, but I don't see the need for generalization
 (DS is really special anyway, and in the BIND 9 implementation it's
 actually the only "at parent" type), so I was just explicit in this
 code.

 BTW: I suspect we need to do the same thing for the database finder.

 This one could also be considered a bug fix, so this is the proposed
 changelog entry:
 {{{
 365.?   [bug]           jinmei
         libdatasrc: in-memory datasource incorrectly returned delegation
         for DS lookups.
         (Trac #1571, git TBD)
 }}}
