Comment (by jinmei):

 trac1431 is ready for review.

 On thinking about the interface further as I wrote the mock
 implementation, I thought the interface could be (hopefully) better
 with some modifications.  So the resulting interface is slightly
 different from the very original one.  See the documentation for
 details.

 One possible controversial point is whether to allow 'known_encloser'
 parameter for possible optimization.  Right now we don't necessarily
 need it because the underlying data source won't be optimized so soon.
 I thought it's quite clear we'll eventually want to provide some
 information that encapsulates data source specific knowledge to
 findNSEC3() once we reach the point of optimizing things and it would
 be nice if the auth code expects it from this stage, but if this
 specific feature is considered premature, I'm okay with removing it
 for now.

 While this is a new API, it's not provide any user visible feature, so
 I don't plan to add changelog for this ticket.
