censor: add exchange tests, via local push/pull and bundle/unbundle

These tests exercise the edge cases of exchanging censored commits between
censor-aware Mercurial clients. These tests do not extend to cover
backwards-compatible exchange; such tests require a script which builds older
versions of Mercurial.

For more background on the censorship feature design, see:
