Make it easier to start using RocksDB Summary: This diff is addressing multiple things with a single goal -- to make RocksDB easier to use: * Add some functions to Options that make RocksDB easier to tune. * Add example code for both simple RocksDB and RocksDB with Column Families. * Rewrite our README.md Regarding Options, I took a stab at something we talked about for a long time: * https://www.facebook.com/groups/rocksdb.dev/permalink/563169950448190/ I added functions: * IncreaseParallelism() -- easy, increases the thread pool and max_background_compactions * OptimizeLevelStyleCompaction(memtable_memory_budget) -- the easiest way to optimize rocksdb for less stalls with level style compaction. This is very likely not ideal configuration. Feel free to suggest improvements. I used some of Mark's suggestions from here: https://github.com/facebook/rocksdb/issues/54 * OptimizeUniversalStyleCompaction(memtable_memory_budget) -- optimize for universal compaction. Test Plan: compiled rocksdb. ran examples. Reviewers: dhruba, MarkCallaghan, haobo, sdong, yhchiang Reviewed By: dhruba CC: leveldb Differential Revision: https://reviews.facebook.net/D18621

Add dual-license info to README.md Summary: From #3417 and after talking to both GitHub and our open source legal team, the recommended approach was to explicitly state the dual-license in the readme. Changing the license files to accommodate the auto-detection is too much of a pain, would involve editing every code file header.
