[PATCH 00/15] Refactor chunk-format into an API

I was thinking about file formats recently and realized that the "chunks"
that are common to the commit-graph and multi-pack-index could inform future
file formats. To make that process easier, let's combine the process of
writing and reading chunks into a common API that both of these existing
formats use.

There is some extra benefit immediately: the writing and reading code for
each gets a bit cleaner. Also, there were different checks in each that made
the process more robust. Now, these share a common set of checks.

In particular, Szeder made some updates to the commit-graph writing process
that forms the model for this API.

Thanks, -Stolee
