I'll send out a new series shortly with those changes.

So I think that the current scope left is best estimated by the
following command:

  git grep -P 'unsigned char\s+(\*|.*20)' | grep -v '^Documentation'

So there are approximately 1200 call sites left, which is quite a bit of
work.  I estimate between the work I've done and other people's
refactoring work (such as the refs backend refactor), we're about 40%
done.

I'm hoping to send out more smaller series in the future, since running
make test on a huge series takes a long time.

Part of the problem is that some places are almost completely
convertible, except for one or two components that rely on something
like sha1_array.  I have patches somewhere that convert that to
oid_array, but I'm not sure how well they'll be received at this point.
I think converting a lot of shallow-related code requires that
conversion, though.
