[PATCH v3 0/4] Misc. fsck.overlay test fixes

[Amir Goldstein <amir73il@gmail.com>]

Eryu,

This is a re-post for zhangyi's fsck.overlay test fixes from
October [1]. Based on my own code review of those patches, I have
made some minor modifications and added some more fixes.

I have been carrying the two patches by zhangyi in my dev branch
for a while. Without them running overlay tests with fsck.overlay
installed is failing some tests.

Zhangyi,

Please review my changes, some based on your suggestions.
Feel free to re-post "fsck.overlay stress test" and
"fsck.overlay exception tests". My goal with this posting
was just to fix failures of existing tests when fsck.overlay
is installed.

Thanks,
Amir.

Changes from v2:
- Dropped patches of new tests
- Move fsck exit code constants to common/config
- Fix _repair_scratch_fs
