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.

with the O_RDONLY flag and issue any ioctl to the device.
