e3a646e4d2 [dbg] Improve error resilience of debugging tools 
Do not open the metadata. The tool interprets user specified blocks one-by-one.
Thus, there's no need to preload the metadata structures.

Also remove the unused --ignore-metadata-space-map option. It was designed
to control the loading of space maps with the old metadata constructors.

58cd881340 Fix regression where era_restore wouldn't work with devices. 
check_file_exists() had an extra parameter added with a default, which was
the wrong default for era_restore.

ba7fd7bd2b [thin_check (rust)] Make --sync-io the default. 
For some systems you have to adjust the ulimits to get io_uring
to work, so we now default to using sync io.

Also added --async-io flag.

565c656ed2 [thin_generate_damage] Do not open a new transaction to prevent ref-count underflow 
There's a chance that thin_generate_damage tries to change ref-counts of
space map blocks due to its random nature, which could lead to problems.
If the ref-counts of metadata space map blocks (shadow source) is changed
to zero, then the ref-counts will become underflow after a shadow operation.

In-place space map modification is a way to prevent that value underflow.
An alternative approach is to avoid changing ref-counts of space map blocks.

1fe8a0dbde [thin_check] Allow using --clear-needs-check and --skip-mappings together 
Although it is not recommended to clear the flag without a full
examination, however, the usage has been documented as an approach
to reduce lvchange run time [1]. For the purpose of backward
compatibility and avoiding boot failure after upgrading thin_check [2],
the limitation is now removed.
