cmdutil: convert the prefetchfiles() hook to a callback mechanism (API) Yuya suggested a list of callbacks instead of function wrapping. This means that one extension can't block another from processing the list. .. api:: File prefetching is now handled by registering a callback with scmutil.fileprefetchhooks.
