recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

swap_pager.c reserves 2 blocks for a bsd label. Change that 2 to the
expression howmany(BBSIZE, PAGE_SIZE), where BBSIZE is the size of the
boot block area. That can be less than 2 if PAGE_SIZE is big.

swapon(8) has an option to trim (delete) all the blocks of a device at
startup. However, if the first of those blocks is a bsd label, then
trimming those blocks is destructive. Change swapon to leave the
first BBSIZE bytes untrimmed.

Update manual pages to reflect changes in how swapon and how it may be
used, espeically in association with savecore.

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.

swap will not be enabled, with `swapon -aL' complaining:

This happens because swap_on_geli_args() which parses geli arguments
out of all mount options does not expect late or noauto among them.
Fix this by explicitly allowing these arguments.

swapoff: Remove only late devices with -aL.

Currently, '/etc/rc.d/swaplate stop' removes all swap devices. This can be
very slow and may not even be possible if there is a lot of swap space in
use. However, removing swap devices is only needed for late swap devices
that may depend on daemons that subsequent shutdown steps stop. Normal swap
devices such as hard disk partitions will remain available throughout the
shutdown process and need not be removed.

In swapoff, interpret -aL to remove late swap devices only, and use this in
etc/rc.d/swaplate. The meaning of -aL in swapon remains unchanged (add all
swap devices, both normal and late).
