[PATCH 0/8] chunk-format: introduce `pair_chunk_expect()` convenience API

[Taylor Blau <me@ttaylorr.com>]

While reviewing this series, I noticed a couple of spots that would be
helped by having a convenience function that stores the start of a
chunk in a designated location *after* checking that the chunk has the
expected size.

I called this function `pair_chunk_expect()` and touched up seven spots
that I think could benefit from having a convenience function like this.

This applies directly on top of 'jk/chunk-bounds'. Thanks in advance for
your review!
