[PATCH 0/3] pack-objects: simplify add_objects_in_unpacked_packs()

[Taylor Blau <me@ttaylorr.com>]

This short series is extracted from mine and Peff's work on cruft packs. These
three patches focus on cleaning up add_objects_in_unpacked_packs(), which is
used to implement `git repack -k`.

The pay-off for this clean-up is significant, though: we net -50 lines of code,
and the result is much more readable, at least in my opinion.

The changes are described in detail in the patch messages, but essentially we
are replacing a loop over get_all_packs() with for_each_packed_object() after
adding a couple of new flags necessary to make the switch. And once we are done
with that, the third patch removes a bit from the object flag allocation table.

Thanks in advance for your review.
