Fix "fasthalt" to halt instead of reboot

fasthalt has behaved like reboot, instead of like halt, since r228408
(2011, 10.0-RELEASE). Fix it. One wonders if anyone will notice.

General 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

Add flag to disable inital reboot(8) userland sync

Add -N flag to reboot(8) which bypasses the userland sync(2) during
reboot(8) while still allow the kernel sync during the reboot(2) syscall
to occur.

An example use of this is when rebooting with disconnected iSCSI sessions
which would otherwise cause the reboot to hang on BIOs that will never
complete.
