Yueh-Hsuan Chiang 647eafdc21 Introduce Lua Extension: RocksLuaCompactionFilter
Summary:
This diff includes an implementation of CompactionFilter that allows
users to write CompactionFilter in Lua.  With this ability, users can
dynamically change compaction filter logic without requiring building
the rocksdb binary and restarting the database.

To compile, WITH_LUA_PATH must be specified to the base directory
of lua.
Closes https://github.com/facebook/rocksdb/pull/1478

# CC C Compiler path
# CXX C++ Compiler path
# PLATFORM_LDFLAGS Linker flags
# JAVA_LDFLAGS Linker flags for RocksDBJava

# PLATFORM_SHARED_EXT Extension for shared libraries

# PLATFORM_CCFLAGS C compiler flags
# PLATFORM_CXXFLAGS C++ compiler flags. Will contain:
# PLATFORM_SHARED_VERSIONED Set to 'true' if platform supports versioned
# shared libraries, empty otherwise.
#
# The PLATFORM_CCFLAGS and PLATFORM_CXXFLAGS might include the following:
#
# -DROCKSDB_PLATFORM_POSIX if posix-platform based
# -DSNAPPY if the Snappy library is present

# Using gflags in rocksdb:
# Our project depends on gflags, which requires users to take some extra steps
# before they can compile the whole repository:
# 1. Install gflags. You may download it from here:
# https://gflags.github.io/gflags/ (Mac users can `brew install gflags`)
# 2. Once installed, add the include path for gflags to your CPATH env var and
# the lib path to LIBRARY_PATH. If installed with default settings, the lib
# will be /usr/local/lib and the include path will be /usr/local/include
