Merge branch 'tb/midx-use-checksum'
When rebuilding the multi-pack index file reusing an existing one,
we used to blindly trust the existing file and ended up carrying
corrupted data into the updated file, which has been corrected.
* tb/midx-use-checksum:
midx: report checksum mismatches during 'verify'
midx: don't reuse corrupt MIDXs when writing
commit-graph: rewrite to use checksum_valid()
csum-file: introduce checksum_valid()
