error: add CensoredNodeError, will be thrown when content deliberately erased

This change introduces the error plus a corresponding catch in dispatch, to
provide localized error messages.

The verb "censor" is used in this commit and all following to refer to erasing
the content of a revlog revision (filelog, for now) without recalculating node
IDs, leaving that revision invalid. Further work must be done to safely share
such revision data with compliant clients.

I find the analogy to censorship straightforward; for less politically
charged options, consider "erase", "excise", "expunge", or "blackhole".
