When a ref is moved or deleted, put it on a list; later, check for reachability Summary: Ref T9028. This allows us to detect when commits are unreachable: - When a ref (tag, branch, etc) is moved or deleted, store the old thing it pointed at in a list. - After discovery, go through the list and check if all the stuff on it is still reachable. - If something isn't, try to follow its ancestors back until we find something that is reachable. - Then, mark everything we found as unreachable. - Finally, rebuild the repository summary table to correct the commit count. Test Plan: - Deleted a ref, ran `pull` + `refs`, saw oldref in database. - Ran `discover`, saw it process the oldref, mark the unreachable commit, and update the summary table. - Visited commit page, saw it properly marked.
