thorpej d622281820 Rework the changer driver a bit:
- Take note of magazine changes, and enqueue "Element Status Changed" events
  that user processes can read or select on.
- Normalize some structure names.
- Report back more status about changer elements:
  * Volume tags (e.g. barcode labels on the backs of your tapes)
  * External device names (for drive units in a changer)
  * Last element a unit of media was moved from
  * Sense information for SCSI changer elements in EXCEPT condition
  * Vendor-specific data if the user requests it.
- Add support for setting volume tags.

gibbs 1b30d7e440 Correct the definition of the changer device capabilities page. The
previous definition confused some reserved bytes for exchange capabilities.

enami d0ad49a001 Backout previous change, and rather, remove all protection but the one
actually currently required.  Suggested by Charles M. Hannum.

bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

thorpej 52fee18c6f New SCSI media changer driver, written from scratch by me. Some
influence from the old driver (written by Stefan Grefen) and from
an autochanger driver written by the Systems Programming Group at the
University of Utah Computer Science Department (currently residing
in src/sys/arch/hp300/dev/ac.c).
