adjustlinkrev: remove unnecessary parameters Since adjustlinkrev has "self", and is a method of a filectx object, it does not need path, filelog, filenode. They can be fetched from the "self" easily.

repair: make strip() return backup file path narrowhg wants to strip some commits and then re-apply them after applying another bundle. Having repair.strip() return the bundle path will be helpful for it.

rebase: check for conflicts before continuing When there are unresolved merge conflicts, there is no reason to make the user wait for rebase to process all of the already rebased commits just to complain that it cannot do anything. Abort early.
