Title: Improve performance when looking up referenced objects.

Avoid a cat-file subprocess call per fat object blob by doing slightly
uglier parsing of "cat-file --batch" that includes object content,
instead of "cat-file --batch-check" that doesn't.

In my ad-hoc testing on a reasonable size repository
(50k rev-list -objects) this speeds up 'git fat status' by almost 40%.
