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.

A long long time ago the register keyword told the compiler to store

for any compiler used in the FreeBSD world today.

am not quite that far). The present pppd seems to work with it just fine

Among the changes are that zlib (aka LZ77 aka deflate aka gzip) compression
is implemented as well as the original compress(1) LZW style.

it's too easy to reproduce ! The only scenario that
I've been able to reproduce the problem under is when
m_len is *exactly* 40 ! So go figure !
