Add quirk entry for a Samsung drive that doesn't like experiencing
the queue full condition.
Bump the timeouts for all probe activities to 60s. We don't know
what the seletion timeout (or equivelent on other mediums) is
for controllers, which can make the transactions at the tail
end of a parallel probe take a while to complete. The DPT
seems to be a card that takes a long time to see a selection timeout.
cam_periph.c:
Don't call a device "gone" after a single selection timeout. We
need to come up with a better policy. Until that time, you'll
have to manually re-scan a bus via camcontrol for the system to
decide that a device is really gone. This should give devices
experiencing temporary insanity to escape death.
wasn't getting sent back for most errors, even if there were retries left
on the command. I'm not sure how I ever let this slip by before...
In any case, we now send back ERESTART if there are retries left for the
command, and send back the default error code when there are no retries
left.

without the DA driver.
The problem was that the CD driver depended on scsi_read_write() and
scsi_start_stop(), which were defined in scsi_da.c.
I moved both functions, and their associated data structures and defines
from scsi_da.* to scsi_all.*. This is technically the "wrong" thing to do
since those commands are really only for direct-access type devices, not
for all SCSI devices. I think, though, that the advantage (allowing people
to compile kernels without the disk driver) outweighs any architectural
purity arguments.

Fix a problem reported by bde: setting SCSI_DELAY to 0 doesn't work. Now,
when the user sets SCSI_DELAY to 0, we re-set it to the minimum allowable
bus settle delay (100ms).
Fix a potential panic in xptfinishconfigfunc() if the CCB passed in is
NULL. Reported by, I think, Nicolas Souchu. Fix a memory leak in the same
function (we created a path, but didn't free it) by allocating the getdev
CCB and path on the stack.

only. Previously, if the device was chmoded 644, someone could open it
with the O_RDONLY flag and issue any ioctl to the device.
