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.

409a660082 [pack/unpack] Get the functional tests working again. 
There's some hard coded version numbers in the tests, but I'm
leaving for now since I'll rewrite in Rust to avoid too much
of a proliferation of languages.

61de3f9287 [thin_metadata_pack/unpack] Replace C++ implementation with a Rust one. 
The Rust implementation is multithreaded, performs better in general and
does custom compression of btree nodes to achieve much better compression
ratios.  unpack also checksums expanded metadata to validate it.

Format version has jumped to 3, no backwards compatibility, but I think
that's ok since we never made a release that contained the C++ version
of these tools.
