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.

The functions that were being compiled into the library have been moved to
scsi_all.c.
One warning: Any programs using scsi_start_stop() or scsi_read_write()
that included scsi_da.h but not scsi_all.h will need to be
changed to include scsi_all.h. This doesn't affect
camcontrol, and I don't think it affects any ports, but you
never know.

Document that SCSI_DELAY is in milliseconds, not seconds.
Tell users that SCSI_CAM is only needed if you've got the QLogic driver in

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.

insertion point that needs to be removed. We then go through a second

through the whole queue which would end up moving the start position in
