Summary: This change has the crash test randomly select from a few file checksum implementations, or nullptr, for DB file_checksum_gen_factory. For compatibility across runs on same DB, each non-null factory can understand all the other functions, but the default changes. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7343 Test Plan: 'make blackbox_crash_test' for a while, including with some debug output to ensure code is being exercised.

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.
