Convert pnmatch to single element array in regexec calls

The regexec function is declared as taking an array of regmatch_t
elements, and passing in the pointer to singleton element, while
correct, triggers a Coverity warning. Convert the singleton into
an array of one to silence the warning.

various: general adoption of SPDX licensing ID tags.

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.
