Copy stable/9 to releng/9.3 as part of the 9.3-RELEASE cycle.

Approved by: re (implicit)
Sponsored by: The FreeBSD Foundation

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.

Correct the type for the global var accessed in sig handlers.

Make signal handler safer.

Submitted by: Jaakko Heinonen <jh@saunalahti.fi>

burncd(8) doesn't handle signals and interrupting burncd during operation.
For example, ^C (SIGINT) may leave the drive spinning and locked.
This may also happen if you try to write a too-large image to a disc
and burncd(8) exits with an I/O error.

Add signal handling by doing a CDRIOCFLUSH ioctl to attempt to leave
burner in a sane state when burning is interrupted with SIGHUP, SIGINT,
SIGTERM, or in case an I/O error occurs during write.
Note, that blanking will still continue after interrupt but it seems to
finish correctly even after burncd(8) has quit.

Also, while I'm here bump WARNS to "6".

Mechanical whitespace cleanup.

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".

On drives that returns 00 as 100% done, lower the criteria
for wraparound, 99 was too much for fast drives since they
do not give 99 as the last value, but instead something
in the 90's range.

Take care of the case for the default speed (no -s option) also.

Move speed units conversion to right before it is used. This catches the
case when the -s option is not used.

Convert speed into KB/s. This was missed by the previous commit to this file.

MFC after: 3 weeks

* Add CDRIOC{READ,WRITE}SPEED ioctls to cd(4). Units are in KB/sec.
* Change atapi-cd ioctls to use the same units.
* Change burncd, cdcontrol to convert CDROM speed to KB/sec before
calling the ioctl. Add a "max" speed option for their command lines.

This change does not break ABI but does change the units passed through
the ioctl so 3rd party software that uses cdrio.h will have to convert
(most likely by multiplying CDROM speed by 177 to get KB/s).

Change the way DAO/TAO modes are init'ed.

Use getprogname(3) instead of hardcoding the name..

Fixes from Ruslan Ermilov:

1. FreeBSD should be spelled with "F" and "BSD" in capitals,
even in comments.

2. Please don't use hard sentence breaks. Always start a
new sentence from the new line.

3. Don't use `#' or `$' in EXAMPLES; this has been fixed
recently in share/examples/mdoc/ templates.

4. Nuke the prog_name variable burncd.c, use getprogname(3).

New option -m to select multisession mode.
WARNING: until now all disks was closed as multisession disks, this is
no longer the case, if the -m option isn't used disks are closed as
singlesession. The reason is that some drives wont close a disk
with one large image on in multisession mode, probably because it
"knows" that a new session wont fit on the media resonably.

Also update burncd with new stuff from various places that I've collected
and modified to my taste, its actually amasing how many thinks up the
same enhancements (none mentioned none forgotten):

Allow '-' to be used as filename for using stdin.

Add 'l' option to take a list of image files from 'filename'

Update to match the progress interface on blank command.

Add msinfo command, used for multisession CD generation with
mkisofs. Gives the last track start LBA, and the next writable LBA.
