Andrew Kryczka 035857a312 Fix RocksDB lite build 
Summary:
NewMemEnv() is defined in rocksdb lite but just returns nullptr --
would it be better to just not define it so we can catch issues like this at
compile-time?

Test Plan:
  $ make clean && OPT="-DTRAVIS -DROCKSDB_LITE" V=1 make -j32 db_test
  $ ./db_test --gtest_filter='DBTest.MemEnvTest'
  ...
  [  PASSED  ] 0 tests.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

Build Status

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 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/
