manifest: speed up matches for large sets of files If the number of files being matched is large, the bisection overhead can dominate, which caused a performance regression for revert --all and histedit. This introduces a (fairly arbitrary) cross-over from using bisections to bulk search.

perf: add methods for timing changeset file list reading

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.

censor: add censor command to hgext with basic client-side tests The censor command is a core extension which can replace the contents of a historical file revision with a censor "tombstone" which can be exchanged with older clients in place of the real revision data. The command rewrites the filelog by copying revision-by-revision. Care must be taken to expand the fulltext of the children of the censored revision before copying them to the new filelog; they might be stored as deltas against the uncensored revision, and those deltas will be invalidated.
