12725983db [block_counter] Add the stop-on-error option to prevent silent errors 
The stop-on-error option aims to solve the lack of damage_visitor support
in space_map::count_metadata and btree counting_visitor. To prevent
possibly silent errors during space map or btree counting, the option
stops the counting process immediately when a btree or bitmap error
was found.

The bitmap blocks are also validated to avoid potential false-alarm,
if broken bitmap is not counted, and the corresponding ref-count is
also zeroed.

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.
