qimport: when mq.secret=True set qimported revision as secret

qrefresh: keep changeset phase during refresh

phases: write default phase data as soon as possible. Marks phase data as dirty when computing default phase. Actual writing is done when the lock is released. So, read only operation don't write phase data because they don't lock the repo.

phase: accept old style revision specification

push: return 1 if no changes found (issue3228) Currently we have the following return codes if nothing is found: commit incoming outgoing pull push intended 1 1 1 1 1 documented 1 1 1 0 1 actual 1 1 1 0 0 This fixes the lower-right entry.

push: more precise failure check on subrepo push This will let us distinguish between nothing to push and push failed

push: return 0 when updating bookmarks

push: fix coding errors in unused branch This branch will get re-enabled in a subsequent fix

bookmarks: move current bookmark on update -u and bare pull -u (issue3222) Currently, this won't update when a #branch spec is in the URL

phases: fix verify with secret csets Verify uses repo.cancopy() to detect whether a repo is a plain old local repo, so it was giving a confusing error message when secret changesets were present.
