Taylor Blau a05f02b1d9 t/helper/test-bitmap.c: add 'dump-hashes' mode
The pack-bitmap writer code is about to learn how to propagate values
from an existing hash-cache. To prepare, teach the test-bitmap helper to
dump the values from a bitmap's hash-cache extension in order to test
those changes.

Taylor Blau 483fa7f42d t/helper/test-bitmap.c: initial commit
Add a new 'bitmap' test-tool which can be used to list the commits that
have received bitmaps.

In theory, a determined tester could run 'git rev-list --test-bitmap
<commit>' to check if '<commit>' received a bitmap or not, since
'--test-bitmap' exits with a non-zero code when it can't find the
requested commit.

But this is a dubious behavior to rely on, since arguably 'git
rev-list' could continue its object walk outside of which commits are
covered by bitmaps.

This will be used to test the behavior of 'pack.preferBitmapTips', which
will be added in the following patch.
