changegroup: remove changegroup dependency from revlog.addgroup
Previously revlog.addgroup would accept a changegroup and a linkmapper and use
it to iterate of the deltas. As part of untangling the revlog-changegroup
interdependency, let's move the changegroup delta iteration logic to it's own
function and pass the simple iterator to the revlog instead.
This will make it easier to introduce non-revlogs stores in the future, without
reinventing any changegroup specific logic.
