Add PS_MODE_NO_KINFO_PROC cmd modifier that indicates that neither
process list should be queried from the kernel, nor list of pids or `-a`
switch provided on the command line to filter the output.

This is intended for use by commands that query information not
neccessary attributed to specific process.

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.
