Summary: Previously, the end key of a range deletion tombstone was considered exclusive for the purposes of deletion, but considered inclusive when checking if two SSTables overlap. For example, an SSTable with a range deletion tombstone [a, b) would be considered overlapping with an SSTable with a range deletion tombstone [b, c). This commit fixes this check.

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.
