Summary: https://github.com/facebook/rocksdb/pull/6383 surfaced an issue with `VersionSet`/`ReactiveVersionSet` and `AtomicGroupReadBuffer::AddEdit` (which was added in https://github.com/facebook/rocksdb/pull/5411): `AddEdit` moves the `VersionEdit` passed to it into `replay_buffer_`, however, the client `VersionSet` classes keep using it afterwards. This *seemed to* work before the refactoring but it really did not: since `VersionEdit` used to have a user-declared destructor, no move constructor/move assignment operator was generated, and the `move` in `AddEdit` was really a copy. The patch makes the copy explicit. Note: it should be possible to rework this logic so that we can get away with the move but for now, this should fix the issue.

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.
