Add a new test-tool helper, name-hash, to output the value of the
name-hash algorithms for the input list of strings, one per line.

I've looked at all 7 patches.

I didn't really understand the concern with shallow in patch 6 (in
particular, the documentation of "git pack-objects --shallow" seems
to imply that it's for use by a server to a shallow client, but at
the point that the server would need such a feature, it probably would
already have bitmaps packed with the new hash algorithm). I didn't look
at it further, though, since I had an algorithm that seemed to also do
OK in the shallow test. So we might be able to drop patch 6.

Other than that, and other than all my comments and Taylor's comments,
this series looks good.
