upgrade: sniff for filelog type The upgrade code should never encounter a vanilla revlog instance: only changelog, manifestrevlog, and filelog should be seen. The previous code assumed !changelog & !manifestrevlog meant file data. So this change feels pretty safe. If nothing else, it will help tease out typing issues.
