so we will be able to address devices larger than the 10-byte cdb's allow
us to do.

fake a geometry. Page 4 info does not get used for size information.
Eliminate now unused union scsi_disk_pages.

have. Some devices return four bytes less information than requested
for the PAGE_RIGID_GEOMETRY page. Put the two together and older
Conner drives don't work because we rejected the short page and asked
for the PAGE_FLEX_GEOMETY page. Noted by hshoexer@ and kettenis@.
Also should fix the problems with a device miod@ reported that did a
similar short PAGE_FLEX_GEOMETRY.

ensure they are the ones requested. No functional change unless
garbage was being returned.

union declaration to allow pointers to individual page types. Simplify
sd.c code by using individual page type pointers. No functional
change.

scsi_disk_pages union. From FreeBSD and SCSI spec.

both 10 byte and 6 byte MODE SENSE commands and just return error
checked values.
Convert sd_scsi.c to use new mechanism for non-optical drives. USB
umass devices will now display actual mode sense info if it is
available via a 10 byte MODE SENSE. Which may mean 0 heads, etc. is
shown until cosmetics are finalized.

1) Correctly define MODE_SENSE_BIG as 0x5a, not 0x54.
2) Delete duplicate #define's of some opcodes in scsi_disk.h.
3) Delete multiple #define's for same opcode in scsi_disk.h.
4) Replace uses of deleted opcodes in umass.c with remaining ones.

Updated ioctls to match
Minor patches in anticipation of wd->sd translation layer

More SCSI logic from NetBSD-current
Some tape fixes. ATAPI tapes do not work yet for most operations.

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.
