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.

fec11289b0 [thin_check/dump] Under populated nodes are now 'non fatal errors' 
thin_dump always ignores non-fatal-errors.

e801cc607b [block_manager] Hard code block size to 4k. 
We're never going to use anything other than 4k, and by hard coding it we
avoid making block_manager a template.
