In this initial version, the "structure" subcommand only surfaces counts
of the various reference and object types in a repository. In a
follow-up series, I would like to introduce additional data points that
are present in git-sizer(1) such as largest objects, combined object
sizes by type, and other general repository shape information.

Some other general features that would be nice to introduce eventually:

- A "level of concern" meter for reported stats. This could indicate to
  users which stats may be worth looking into further.
- Links to OIDs of interesting objects that correspond to certain stats.
- Options to limit which references to use when evaluating the
  repository.

Changes since V5:
- Instead of using `filter_refs()` to get an array of all references, we
  now use `refs_for_each_ref()` to count references, and setup OIDs for
  the path walk, in place. Doing this not only allows us to avoid
  wasting memory storing all the reference info, but also to display
  progress info to the user while iterating across the references
  initially.
- Add a prepatory patch to export `ref_kind_from_refname()` via
  "ref_filter.h" so we can reuse logic to categorize references while
  counting.

This round looked pretty well done to me.  Shall we declare victory
and mark it for 'next' real soon now?

Agreed, I also think that this round looks good and is ready to be
merged down to next.

Thanks!
