Summary: For testing backups, we needed an Env that is fully isolated from other Envs on the same machine. Our in-memory Envs (MockEnv and InMemoryEnv) were insufficient because they don't implement most directory operations. This diff introduces a new Env, "ChrootEnv", that translates paths such that the chroot directory appears to be the root directory. This way, multiple Envs can be isolated in the filesystem by using different chroot directories. Since we use the filesystem, all directory operations are trivially supported. Test Plan: I parameterized the existing EnvPosixTest so it runs tests on ChrootEnv except the ioctl-related cases.

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 specially suitable for storing multiple terabytes of data in a single database.

The public interface is in include/. Callers should not include or
