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.

45a5dc937d Add a -q flag to swapon(8) to suppress informational messages. Use it in
rc.d.
Note: errors are not affected by this flag.

2e64768c87 - Change the meaning of -h flag from giving the output in megabytes to
giving the output in a human-readable form. This behaviour is consistent
  with most of system tools.
- Add -m and -g options to give output in megabytes and gigabytes
  respectively.

a420c8119a Add 'swapctl' - as a hardlink to swapon/swapoff, and augment swapon with
swapctl functionality.  The idea is to create a swapctl command that is
fairly close to the OpenBSD and NetBSD version.  FreeBSD does not implement
swap priority (and it would be a mistake if we did) so we didn't bother with
that part of it.

9eac7384ba correct wording in BUGS section; it's not possible to dismount swap
devices, but it's certainly possible to make use of them.

Boy, I'm glad we're not using sup anymore.  This update would have been
