tested both in the kernel and in userland. Also, fix a couple of printf
warnings that show up when CAMDEBUG is defined.

block descriptors enabled on mode sense commands.
Basically, we try sending a mode sense with block descriptors disabled (the
previous default), and if it fails, we try sending the mode sense with
block descriptors enabled. If that works, we note that in a runtime quirk
entry, so we don't bother disabling block descriptors again for the device.
This problem was first reported by Chris Jones <cjones@honors.montana.edu>
on one of the NetBSD lists, but I'd imagine that some FreeBSD users would
have run into it eventually as well, since our changer driver is derived
form the NetBSD changer driver.
Also, change some of the probe logic so that we do the right thing in the
case of a failure to attach.
Fix a memory leak in chgetparams().
Add a couple of inline helper functions to scsi_all.h to correctly return
the start of a mode page.

not be retried again, even if the SF_NO_PRINT flag is set.

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.
