various: general adoption of SPDX licensing ID tags.

2017-11-27T15:37:16Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. 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. No functional change intended.

Non-tests/... changes: - Add HAS_TESTS= to Makefiles with libraries and programs to enable iteration and propagate the appropriate environment down to *.test.mk. tests/... changes: - Add appropriate support Makefile.inc's to set HAS_TESTS in a minimal manner, since tests/... is a special subdirectory tree compared to the others.
