[PATCH 2 of 5 flagprocessor v6] revlog: add 'raw' argument to revision and _addrevision

The actual rawrevision() method is simply a personal preference as I like
to have simpler apis on operations with optional arguments and I've seen
this in other places, but I do not feel strongly about moving it to use the
raw argument in calls to revision directly. Let me know what you prefer.
