revlog: special case expanding full-replacement deltas received by exchange

When a delta received through exchange is added to a revlog, it will very
often be expanded to a full text by applying the delta to its base. If
that delta is of a particular form, we can avoid decoding the base revision.
This avoids an exception if the base revision is censored.

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