Merge branch 'jk/verify-packfile-gently' into maint

A low-level function verify_packfile() was meant to show errors
that were detected without dying itself, but under some conditions
it didn't and died instead, which has been fixed.

* jk/verify-packfile-gently:
verify_packfile: check pack validity before accessing data
