 We need to extend the in-memory data source implementation so we
 can incrementally update existing data after DDNS or IXFR-in.
 Several things have to be considered:

 - "merge" and "subtract" interface for `RdataSet`.  Regarding merge,
   we also need to avoid having duplicate RDATAs.
 - removing names from `DomainTree`
 - making sure a name is removed from `DomainTree` when its `RdataSet`s
   are removed
 - inter module protocol for updates (in particular, DDNS/xfrin and auth)
 - extend `datasrc::ClientList` class to support updates
 - update auth/DDNS/xfrin to implement these
 - (there should be more)

 The goal of this ticket is to have these discussions, led by someone
 with initial proposals, and create specific development tickets.
