Summary: The patch does some cleanup in and around the legacy `BlobLogReader` class: * It renames the class to `BlobLogSequentialReader` to emphasize that it is for sequentially iterating through blobs in a blob file, as opposed to doing random point reads using `BlobIndex`es (which is `BlobFileReader`'s jurisdiction). * It removes some dead code from the old BlobDB implementation that references `BlobLogReader` (namely the method `BlobFile::OpenRandomAccessReader`). * It cleans up some `#include`s and forward declarations. * It fixes some incorrect/outdated comments related to the reader class. * It adds a few assertions to the `Read` methods of the class.

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.
