* Cleanup and reorg of lib/common

- remove stale code in helper.cpp
- move helper.hpp to demangle.hpp
- move helper.cpp to demangle.cpp
- update CMakeLists.txt with new filenames
- fix includes in config.cpp

* Remove log.hpp and join.hpp

- replace with glog and fmt

* Update lib/common/environment

- move implementation functions into cpp file

* Common library tests

- tests for demangling
- tests for mpl (template metaprogramming)
- tests for environment
