Re: [PATCH 0/9] midx: implement a multi-pack reverse index

This series describes and implements a reverse index for the multi-pack index,

The details of the pseudo-pack, and multi-pack reverse index are laid out in
detail in the sixth patch.

This is in support of multi-pack reachability bitmaps, which contain objects
from the multi-pack index. Likewise, an object's bit position in a multi-pack
reachability bitmap is determined by its position with that multi-pack index's
pseudo pack.

This has been a lot of work, but I'm impressed with the progress here.

This series is good prep, and my comments are very minor.

Since the need for these multi-pack-index-<hash>.rev files doesn't show
up until the reachability bitmaps can be paired with MIDX files, it
would make sense to hold this series in 'next' until that one also
stabilizes and they merge to 'master' together.
