b278f4ffa4 [thin_check] Change the policy of --clear-needs-check-flag to prevent error recurrence 
- Disallow clearing the needs_check flag if there's any error,
  i.e., the metadata must be fully examined, and the result must
  be NO_ERROR.
- Disallow combining --clear-needs-check with -m, --super-blocks-only,
  --skip-mappings, --override-mapping-root, or --ignore-non-fatal-errors.

49efa06ffa [thin_check] Support fixing leaked metadata blocks 
- The leaked blocks are defined as allocated but not used ones,
  i.e., expected ref-count == 0 and actual ref-count <= 2.
- Blocks with expected ref-count > 0, or actual ref-count > 2,
  are treated as unrepairable leaks.
- The fixing processing won't be executed if there's any
  unrepairable leak or errors.
- The fixing process implicitly clearing the superblock
  needs_check flag if there's no error.

7243f95380 [thin_check (rust)] Drop nr threads down to 4 
We get very little benefit from threads atm.  Need to improve IO handling first.

4f120911d2 [thin_check (rust)] First attempt at multithreading the tree walking. 
Still using a single io engine, so little benefit.
