Summary: Fix unstable floating point exception, tested on Windows, 64-bit build. The problem appeared in `SetCapacity()` method at line `high_pri_pool_capacity_ = capacity_ * high_pri_pool_ratio_;` `high_pri_pool_ratio_` was not initialized at that moment, because `SetHighPriorityPoolRatio()` is called after `SetCapacity()`. So, `high_pri_pool_ratio_` contained garbage, which caused "Floating point exception" sometimes.

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.
