Fosco Marotto 3462c94be7 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.
Closes https://github.com/facebook/rocksdb/pull/3541

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.
Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples
See the [github wiki](https://github.com/facebook/rocksdb/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/
