revlog: add a callback "tracking" duplicate node addition If a changegroup contains node already added to the repository, they will be skipped. Skipping them is the right behavior (we don't need to store things twice), but it can hide some information to the code doing the unbundle (eg: shelve looking for the tip of the bundle). The first step to improve this situation is to add a low level callback. We do not need this tracking on all revlog, so actual tracking will be added in the next changeset.
