Russell Belfer 9950d27ab6 Clean up iterator APIs
This removes the need to explicitly pass the repo into iterators
where the repo is implied by the other parameters.  This moves
the repo to be owned by the parent struct.  Also, this has some
iterator related updates to the internal diff API to lay the
groundwork for checkout improvements.
