Log:
  General further adoption of SPDX licensing ID tags.
  
  Mainly focus on files that use BSD 3-Clause license.
  
  The Software Package Data Exchange (SPDX) group provides a specification
  to make it easier for automated tools to detect and summarize well known
  opensource licenses. We are gradually adopting the specification, noting
  that the tags are considered only advisory and do not, in any way,
  superceed or replace the license texts.
  
  Special thanks to Wind River for providing access to "The Duke of
  Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
  starting point.
