Summary: We can only check key on restored backup if in a stress test configuration locking the key. (Fixes mismatch seen in backup/restore with atomic flush.) TestCheckpoint used a very ugly solution to the same problem: copy-paste dozens of lines of code with some changes and removals. I removed the unnecessary implementation and made the existing one simply adaptive, like TestBackupRestore. Also made TestBackupRestore clean up dead backup/restore directories on success.

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.
