revert: add a way for external extensions to prefetch file data
This allow extensions that mess with the storage layer (remotefilelog,
largefile) to prefetch any data that will be accessed during the revert
operation.
We are currently fetching more data than theoretically required because the
backup code is a bit stupid. Future patches will improve that.
