Summary: As described in https://github.com/facebook/rocksdb/issues/563, we should add minor version to SONAME, since we break ABI with minor releases. I also turned PLATFORM_SHARED_VERSIONED to true by default. This is true in LevelDB and it was switched to false by D15117 for no apparent reason. It should only be false for iOS. Test Plan: `make shared_lib` produced librocksdb.dylib.3.10.0 Reviewers: sdong, yhchiang, meyering Reviewed By: meyering Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D36573

# before they can compile the whole repository:
|

# 1. Install gflags. You may download it from here:

|
# https://code.google.com/p/gflags/
|
|
# 2. Once install, add the include path/lib path for gflags to CPATH and
|
|
# LIBRARY_PATH respectively. If installed with default mode, the
|
|
# lib and include path will be /usr/local/lib and /usr/local/include
|
|
# Mac user can do this by having brew installed and running brew install gflags
