revlog: extend addgroup() with callback for duplicates

The addgroup() interface currently doesn't allow the caller to keep
track of duplicated nodes except by looking at the returned node list.
Add an optional second callback for this purpose and change the return
type to a boolean. This allows follow-up changes to use more efficient
storage for the node list in places that are memory-sensitive.
