Revert convert-repo changes

fix hgrc doc hook descriptions.

hooks: distinguish between locally committed and incoming changes. "commit" hook is now for locally committed changes only. "incoming" is for changes pulled, pushed, or unbundled into local repo.

Allow callers to pass in the dirstate lock in most localrepo.py funcs. This makes it possible to take the lock once and commit a large number of patches, without having to read and write the dirstate for each patch.

revlog.strip should clear the chunkcache The chunkcache isn't valid after a strip, it needs to be cleared out.

Show "(No help text available)" for commands without doc string. Currently this only occurs with "hg help qcommit" from mq extension.

Create default commit message in a more pythonic way.

Removed "HG: manifest hash" line from commit message.

Put the empty line in commit text above the branch merge line.

Run commit message editor in the repo root (like hooks). This makes the hgeditor script work with hg commit -R path/to/repo
