[PATCH 00/11] Add 'git multi-pack-index verify' command




The multi-pack-index file provides faster lookups in repos with many
packfiles by duplicating the information from multiple pack-indexes into a
single file. This series allows us to verify a multi-pack-index using 'git
multi-pack-index verify' and 'git fsck' (when core.multiPackIndex is true).

The pattern for the tests is similar to that found in t5318-commit-graph.sh.

During testing, I found a bug in how we check for the size of off_t (we are
not actually checking off_t, but instead uint32_t). See "multi-pack-index:
fix 32-bit vs 64-bit size check".

Thanks to Ævar [1], I added a commit that provides progress updates when
checking object offsets.

Based on ds/multi-pack-index
