[PATCH 0/4] fsck improvements

So I looked at fsck to see if it's easy to support multithread and found out I could reduce fsck time by half. So here it is. I think I haven't made any mistakes but fsck is not my domain.

The last patch is reposted because it conflicts with the series. It also prints progress when checking connnectivity.

  fsck: return error code when verify_pack() goes wrong
  Stop verify_packfile() as soon as an error occurs
  fsck: avoid reading every object twice
  fsck: print progress
