[JGIT PATCH 00/10] Support writing pack index version 2

["Shawn O. Pearce" <spearce@spearce.org>]

This series adds support for writing pack index v2 formatted files
out of IndexPack, and thus any pack we fetch over the network.  It
also abstracts out the index formatting functions so we can reuse
them efficiently inside of PackWriter to support creating packs on
the local disk, or to upload packs directly over a dumb transport.

I started down this path because we're missing index v2 support and
that is likely to become a default in the near future for C Git,
and because I want to support push over sftp style URLs now that
Marek has a pack writing implementation.
