[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.

[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.

[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.
