command on drives that don't like it. Right now, there's just a bogus
quirk entry in the table that doesn't do anything, but that should be
changed once we get actual inquiry data for drives that don't like the
synchronize cache command.
Also, add a shutdown hook that runs through all direct access peripherals
and runs a synchronize cache on them if they're still open, and if
synchronize cache isn't disabled via a quirk entry.
Add a synchronize cache call at the end of dadump() (again, conditionalized
on the quirk entry), so we can insure that the disk cache contents get
flushed to physical media after a dump.
Check the new quirk entry in daclose() to decide whether or not to
synchronize the cache for a disk at final close.

well) Among them:
[ cd driver ]
1. Old labeling code was still there.
2. Error handling for dsopen() was broken (no test for the `error'
returned by dsopen(); bogus test of an `error' that is known to be 0).
3. cdopen() closed the physical device after certain errors although there
may still be open partitions on it.
4. cdclose() closed the physical device although there may still be open
partitions on it.
5. Some printf format fixes was incomplete or missing.
6. cdioctl() truncated unit numbers mod 256.
7. cdioctl() was missing locking.
[ da driver ]
1. daclose() closed the physical device although there may still be open
partitions on it. This was fixed many years ago in sd.c rev.1.57.
2. A minor optimization (the dk_slices != NULL test) in sdopen() became
uglier in daopen(). It is not worth doing. da only regressed compared
with od and my version of sd, since I never committed the change to sd.
daopen() should probably do less if some partition is already open.
This is not addressed by the diffs.

- Added a getdev CCB call in the cdopen() and daopen() calls so that the
vendor name and device name are available for the disklabel. (suggested
by bde)
- Removed vestigal devfs support in both drivers, since we can't properly
work with devfs yet. (ask bde for details on this)
- Cleaned up the probe code in both drivers in the failure cases. There
were a number of things wrong here. The peripheral driver instances
weren't getting properly cleaned up. Sometimes the wrong probe message
would get printed out (with the failure message appended), so it wasn't
very clear that we failed to attach. SCSI sense information was printed,
even when the error in question wasn't a SCSI error. I put similar fixes
into the changer driver in revision 1.2 of scsi_ch.c.
