Summary: - Add a controlled async filesystem regression test for released direct I/O async reads, verifying released handles are aborted before a later `Poll()` can complete them. - Add a MultiScan-style regression test for skipping a pending range remainder before seeking into a later async read. - Extend db_stress/crashtest coverage so MultiScan can stop early after `--num_iterations` results and randomize `--multiscan_use_async_io` again.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
