* Move the existing apache commons jars to a subfolder in the lib
  directory.
* Add the license file in the apache commons folder and include it in
  the build variants.
* Add the apache commons lang3 library that can be used in parallel to
  the older lang library due to different namespaces. It will be applied
  for differentiating between recent OSes, for instance.
