lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33+00:00

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.

Const poisoning.

Fix problems people were having with large -O levels with GCC and

getting libutil/libcrypt to work properly.  I've determined that GCC
thinks it can inline all functions, including weak-symboled ones, if
it feels like it.

Create a new stub.c and move any stubs there to prevent inlining.
Thanks to jdp and William S. Duncanson for helping me finally find the
problem.

Add weak symbol pragma for crypt_set_format().
