[PATCH 0/9] more robustness against pack corruptions

A few months ago I produced a set of patches to allow git to work even in the presence of pack corruption given that the corrupted objects have a good duplicate in the object store. Turns out that this work was rather incomplete and covered only a limited set of cases.

This series extend coverage to all cases I could think about, and make repack-objects able to create a good pack in such conditions to "fix" the corruption without having to perform a full repack.

Yes, this is all about the small and trivial patch I posted a while ago that I intended to repost with a test case. Well, the test failed miserably, resulting in this series before it finally all passed. ;-)
