[PATCH 1/6] commit_graft_pos(): take an oid instead of a bare hash

From

All of our callers have an object_id, and are just dereferencing the hash field to pass to us. Let's take the actual object_id instead. We still access the hash to pass to hash_pos, but it's a step in the right direction.

This makes the callers slightly simpler, but also gets rid of the untyped pointer, as well as the now-inaccurate name "sha1".

I think this one is an obvious cleanup that we'd want whether we go
further in the series or not.
