confusing when trying to attach scsibus to a hba, since it is really meant
for attaching scsi devices to scsibus.

asc/ascq handling to deal with the pair together rather than seperately, since
modern scsi has long since polluted the "categories" of asc enough that you
pretty much need to always look as ascq.

"becoming ready" - this is done in the exact same way that it
was done for tape in st.c. This commit adds a cd specific interpret_sense
routine to cd.c that will catch the becoming ready case and handle it.
This also removes the need to use crazy timeouts to catch this case.

diagnostic type printf spew that is useful into #ifdef CHANGER_DEBUG,
removes some that is pretty much useless, and changes one instance
of using kernel printf to indicate the truncation of a result due to the
provided buffer being too small into a return of EINVAL back to the caller.

and adapted from FreeBSD. This adds the ability for status requests to ask
for the volume tags (usually bar codes, on changers with a bar code reader)
on media inthe library.

1) Don't use SCSI_IGNORE_NOT_READY when doing test_unit ready to wait for
the device to come up.
2) use SCSI_IGNORE_ILLEGAL_REQUEST when doing test_unit_ready to wait for
the device to come up (just as is done in st(4))
3) add a ch_interpret_sense routing to perform special handling of
the case where the unit is in the process of becoming ready. Hope springs
eternal, that if the device tells us it is trying to become ready, then
we should wait for it to do so, however long it takes (and on tape library
scans this can take a while - i.e. a few minutes for large libraries).
The custom handler ensures that the retry count is not decremented in
this case and this case only.

atapi_mode_[sense|select](). This will allow the removal of
atapi_base.c and atapi_all.h files, and sets the stage for better usb
mode sense handling amoung other things.
Remove cd_scsibus_[get|set]_mode() and
sd_scsibus_mode_sense() shims in favour of scsi_mode_[sense|select]().
Add zero'ing of reserved length field in scsi_mode_select(). Change
some uchar * type parameters to scsi_mode_header *.
No functional changes. Mostly from NetBSD.

Eliminate some duplicate structures and defines along the way. SCSI CD
drives will now pay attention to the 'flags' parameter for MODE SENSE
and MODE SELECT commands. No other functional change.

submitted via ioctl. Eliminate scsi_do_safeioctl(), thus permitting
ch, ss and st devices to submit SCSI commands. Return EPERM rather
than EBADF when permissions are inadequate.
Allows more programs to run with fewer permissions. Problem diagnosed
by Nikolay Sturm in mplayer port.

Use increased retries number and don't ignore SCSI_IGNORE_NOT_READY
when call scsi_test_unit_ready() for cd-rom, this makes system wait
if drive is loading media.

process finding out the changer parameters.
Print out changer parameters only if they're changed from the last
read of changer parameters. This works for the first time, and for
99.9% of all other cases will be silent ever after. The only time
this will then be chatty afterwards is if you change something
within the changer (add a drive, etc.).

to:
* New changer driver.
* Better optical support.
* Different `done' semantics.
* New quirks for SCSI QIC tape driver, SCSI floppy drives.
* Better support for SCSI-I devices.
Everybody needs to test this.
