Old scsi error printing code is now gone.

default. Use "option SCSIVERBOSE=0" to turn off (only added 8Kb to my kernel).
From the NetBSD commit message:
Add in more detailed SCSI error printing, based off of final SCSI-2 spec.
This will also print out things like progress indicator errors, and will
also dump out additional sense bytes that haven't been decoded.

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.

to 8 internally so that drivers do not need to init it for regular scsi :-)

* Implemented NetBSD PR#2529, adding ZIP 100.
* Added MTIOCTOP support to acd, cd, and sd.
* Implemented eject on close for acd, cd, and sd.
`mt -f /dev/rcd0d offline' now ejects a mounted {acd|cd|sd} when it is
unmounted.

- scsi prototypes.
- Add SCSI scanner support by Kenneth Stailey and Joachim Koenig-Baltes,
hacked a but. Needs more work.
ss.c:
- Truncate to the window size in ssminphys(), not ssread().
- Missed some prototyping foo.
- Minor tweak; make sure window size is 0 on close.
- Change variable name to avoid GCC warning.
- Handle EOF a little differently.

"command aborted" status)
Handle cases like the following:
- controller calls scsi_done() with error XS_TIMEOUT
- scsi_done() calls sddone()
- sddone() calls disk_unbusy()
- scsi_done() calls controller to retry command (missing the
call to disk_busy())
- controller calls scsi_done()
- scsi_done() calls sddone()
- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.
