Summary: In patch https://reviews.facebook.net/D47067, we change the log level of the initial database information to header level. As a result, even when the InfoLogLevel is set to Fatal, the LOG file of a newly opened rocksdb instance will not be empty. However, the current InfoLogLevelTest expect it should be empty. This patch fixes this issue by enabling InfoLogLevelTest to ignore the Log header.

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

internal APIs may be changed without warning.
