2860b4c0b1 [thin_check] rename --fix-metadata-leaks to --auto-repair 
This flag will cover all trivial fixes, such as data leaks.

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.

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.

5d28c05dc3 [thin_check] detail and mapping trees weren't being counted properly for the metadata snap. 
This could result in block counts being unexpectedly non zero.

a7c96c0e1e [everything] Fix circular shared pointer references. 
We had a cycle from transaction_manager <-> space_map, and also from
the ref_counters back up to the tm.

This prevented objects being destroyed when various programs exited.

From now on we'll try and only use a shared ptr if ownership is
implied.  Otherwise a reference will be used (eg, for up pointers).
