Add a "kern.features.ata_cam" sysctl in the kernel when the ATA_CAM kernel
option is defined. This sysctl can be queried by feature_present(3).

Query for this feature in /sbin/atacontrol and /usr/sbin/burncd.
If these utilities detect that ATA_CAM is enabled, then these utilities
will error out. These utilities are compatible with the old ATA
driver, but are incomptible with the new ATA_CAM driver. By erroring out,
we give end-users an idea as to what remedies to use, and reduce the need for them
to file PR's. For atacontrol, camcontrol must be used instead,
and for burncd, alternative utilties from the ports collection must be used
such as sysutils/cdrtools.

In future, maybe someone can re-write burncd to work with ATA_CAM,
but at least for now, we give a somewhat useful error message to end users.

Fix the fallouts from r146267:

- Add the forgotten "mode" argument to the "mode" command.
- Move the description of "info" to where it belongs.

Document spindown constraints as given in the original commit

Add a "spindown" facility to ata-disks: If no requests have been received
for a configurable number of seconds, spin the disk down. Spin it back
up on the next request.

Notice that the timeout is only armed by a request, so to spin down a
disk you may have to do:

atacontrol spindown ad10 5
dd if=/dev/ad10 of=/dev/null count=1

To disable spindown, set timeout to zero:

atacontrol spindown ad10 0

In order to debug any trouble caused, this code is somewhat noisy on the
console.

Enabling spindown on a disk containing / or /var/log/messages is not
going to do anything sensible.

Spinning a disk up and down all the time will wear it out, use sensibly.

Incorporate most of Ruslans changes plus minor addtion by me

Back out ru's changes. Soren has requested this and I see no reason
to not just do it. It is his new code that is being actively
developed so he has say over it. ru's direct changes were premature
as they occurred less than 4 hours after it was committed to the tree.

Make this compile with ${BDECFLAGS}, apply style(9), cleanup manpage.

Add atacontrol, a util to control variuos aspects of the ATA.4 driver,
please consult atacontrol.8 for usage..
