[PATCHv3 0/9] object store: oid_object_info is the next contender

v3:
* fixed and extended the commit message of last commit
* fixed the last patch, as Jonathan Tan suggested, see interdiff:

v2:

* fixed the sha1/oid typo
* removed spurious new line
* Brandon and Jonthan discovered another dependency that I missed due
  to cherrypicking that commit from a tree before partial clone was a thing.
  We error out when attempting to use fetch_object for repos that are not
  the_repository.

Thanks, Stefan

v1: This applies on top of origin/sb/object-store-replace and is available as https://github.com/stefanbeller/git/tree/oid_object_info

This continues the work of sb/packfiles-in-repository, extending the layer at which we have to pass in an explicit repository object to oid_object_info.

A test merge to next shows only a minor merge conflicit (adding different #include lines in one c file), so this might be a good next step for the object store series.

Notes on further object store series: I plan on converting the "parsed object store" next, which would be {alloc, object, tree, commit, tag}.c as that is a prerequisite for migrating shallow (which is intermingled with grafts) information to the object store.

There is currently work going on in allocation (mempool - Jameson Miller) and grafts (deprecate grafts - DScho), which is why I am sending this series first. I think it can go in parallel to the "parsed object store" that is coming next.

Thanks, Stefan
