revlog: _addrevision creates full-replace deltas based on censored revisions

A delta against a censored revision is either received through exchange and
written blindly to a revlog, or it is created by the revlog itself. This
change ensures the latter process creates deltas which fully replace all
data in a censored base using a single patch operation.

Recipients of a delta against a censored base will verify that the delta is in
this full-replace format. Other recipients will use the delta as normal.

For background and broader design of the censorship feature, see:
