brian m. carlson 2dacf26d09 pack-objects: use --objects-edge-aggressive for shallow repos ...

When fetching into or pushing from a shallow repository, we want to
aggressively mark edges as uninteresting, since this decreases the pack
size.  However, aggressively marking edges can negatively affect
performance on large non-shallow repositories with lots of refs.

Teach pack-objects a --shallow option to indicate that we're pushing
from or fetching into a shallow repository.  Use
--objects-edge-aggressive only for shallow repositories and otherwise
use --objects-edge, which performs better in the general case.  Update
the callers to pass the --shallow option when they are dealing with a
shallow repository.
