help: add --keyword (-k) for searching help
hgweb: side-by-side comparison functionality

Mercurial can now identify third-party extensions as sources of tracebacks
outgoing: accept revset argument for --rev
performance improvement on branchy repo: incrementaly update branchcache

performance improvement for huge .hgignore: process regex with re2 bindings if available
revset: add "diff" field to "matching" predicate
revset: add "converted" predicate to find converted changesets
revset: add "origin" and "destination" predicates, to get graft, transplant or rebase origins or destinations.
