Yueh-Hsuan Chiang 2082a7d745 [Java] Temporary set the number of BG threads based on the number of BG compactions. 
Summary:
Before the Java binding for Env is ready, Java developers have no way to
control the number of background threads.  This diff provides a temporary
solution where RocksDB.setMaxBackgroundCompactions() will affect the
number of background threads.

Note that once Env is ready.  Changes made in this diff should be reverted.

Test Plan:
make rocksdbjava
make jtest
make jdb_bench
java/jdb_bench.sh

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 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 an 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.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See doc/index.html and github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
