8a16b7a18f 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.

8d27c2000b Fix late and noauto with geli swap
With the following in /etc/fstab:

/dev/gpt/swap.eli none swap sw,late 0 0

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

swapon: Invalid option: late

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.

fbbd9655e5 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.

7627b33010 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).

e47c947e6e Stop using the non-standard basename_r() function.
This change makes the code use the POSIX basename() function. It has the
advantage that (if implemented correctly), it also imposes no restrict
on the pathname length.

Notice that I haven't added any error handling to the strdup() call. It
looks like none of the other calls to strdup() and malloc() performed by
this utility do it either.

8f8de1e127 - Modify swapon(8) so that it uses most of geli(8) defaults for swap,
which is presently: AES-XTS, no authentication.  Create provider
   with pagesize as sectorsize by default.
 - Rewrite parsing code for geli(8)-backed swap options, now options
   are required to be exact match, and unrecognized options will trigger
   a warning.
 - Don't initialize GELI device if it's already initialized.  This
   restores previous behavior.
 - Don't duplicate file descriptor when working with geli(8) and
   gbde(8) as there is no need to communicate with the utility other
   than exit status.
 - When calling swap_on_off_* routines, which_prog can only be SWAP_ON
   or SWAP_OFF.  Eliminate unneeded case branches by replacing switch
   with if's.
 - Plug a few memory leaks.

268a55bc98 - Add vnode-backed swap space specification support. This is enabled when
device names "md" or "md[0-9]*" and a "file" option are specified in
  /etc/fstab like this:

  md    none    swap    sw,file=/swap.bin       0       0

- Add GBDE/GELI encrypted swap space specification support, which
  rc.d/encswap supported.  The /etc/fstab lines are like the following:

  /dev/ada1p1.bde       none    swap    sw      0       0
  /dev/ada1p2.eli       none    swap    sw      0       0

  .eli devices accepts aalgo, ealgo, keylen, and sectorsize as options.

  swapctl(8) can understand an encrypted device in the command line
  like this:

  # swapctl -a /dev/ada2p1.bde

- "-L" flag is added to support "late" option to defer swapon until
  rc.d/mountlate runs.

- rc.d script change:

    rc.d/encswap -> removed
    rc.d/addswap -> just display a warning message if $swapfile is defined
    rc.d/swap1 -> renamed to rc.d/swap
    rc.d/swaplate -> newly added to support "late" option

These changes alleviate a race condition between device creation/removal
and swapon/swapoff.

16fc3635f7 Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".
