f4c3098e02 [thin_check (rust)] fix bug in key range splitting. 
Ranges were not being ommitted when a block was ommitted due to
being shared and already visited.

cda92de441 [thin_check (rust)] Add a threaded version of btree walk. 
Bottom level mappings use this if there are few devices.  Performance
is a bit slower for io_uring, and much slower for sync io (which I think
is due to io scheduling which I can't do much about).
