Summary: This change adds a Dynamic Library class to the RocksDB Env. Dynamic libraries are populated via the Env::LoadLibrary method. The addition of dynamic library support allows for a few different features to be developed: 1. The compression code can be changed to use dynamic library support. This would allow RocksDB to determine at run-time what compression packages were installed. This change would eliminate the need to make sure the build-time and run-time environment had the same library set. It would also simplify some of the Java build issues (where it attempts to build and include various packages inside the RocksDB jars). 2. Along with other features (to be provided in a subsequent PR), this change would allow code/configurations to be added to RocksDB at run-time. For example, the build system includes code for building an "rados" environment and adding "Cassandra" features. Instead of these extensions being built into the base RocksDB code, these extensions could be loaded at run-time as required/appropriate, either by configuration or explicitly. We intend to push out other changes in support of the extending RocksDB at run-time via configurations.

# before they can compile the whole repository:

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

# 2. Once installed, add the include path for gflags to your CPATH env var and

# will be /usr/local/lib and the include path will be /usr/local/include
