Re: non-smooth progress indication for git fsck and git gc

That code isn't lib-ified enough to be run in process, but I think the
patch below should give similar behavior to what fsck currently does.
We'd need to tell index-pack to use our fsck.* config for its checks, I
imagine. The progress here is still per-pack, but I think we could pass
in sufficient information to have it do one continuous meter across all
of the packs (see the in-code comment).

And it makes the result multi-threaded, and lets us drop a bunch of
duplicate code.

The numbers here are nice, even to readers who do not necessarily
care about the progress meter output ;-)
