sys: 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.

This is work done by Michael Tuexen and myself at the IETF. This
adds the new I-Data (Interleaved Data) message. This allows a user
to be able to have complete freedom from Head Of Line blocking that
was previously there due to the in-ability to send multiple large
messages without the TSN's being in sequence. The code as been
tested with Michaels various packet drill scripts as well as
inter-networking between the IETF's location in Argentina and Germany.
