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.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Hide struct pcb definition by #ifdef __amd64__ braces. If cc -m32
compilation results in inclusion of the header, a confict arises due
to savefpu being union for i386, but used as struct in the pcb
definition. The 32bit code should not need amd64 variant of the
struct pcb anyway.

For struct region_descriptor, use __uint64_t instead of unsigned long,
as the base type for bit-fields. Unsigned long cannot have width 64
for -m32.

The changes allowed to use sys/sysctl.h for cc -m32.
