Rewrote CMake build script.

This should take care of existing build and linker issues. Standard OpenSSL and Protobuf libraries are no longer statically linked into the kinetic library but are normal dependencies. Removed dependency on gtest / gmock when not building the test system. Added cmake options to control linking of glog and gflag libraries and optionally handle openssl thread safety in the client. Removed some historical (now unused?) build features to simplify the build process, will re-add if anybody has demand for a feature.
