If SCSI_IGNORE_ILLEGAL_REQUEST is set no error is returned from scsi_xs_sync()
when the request is unsupported.

So check mode sense(6) and mode sense(10) results for valid headers before
passing the results back.

Avoid overwriting any error that was returned.

Rename SID_INQUIRY_HDR (a.k.a. 5) to more explicit SID_SCSI2_HDRLEN and use it
to replace various uses of '5' when calculating the amount of data in the
INQUIRY response. Matches up more naturally with SID_SCSI2_ALEN.

Also use to fix SCSIDEBUG display of INQUIRY responses to show correct count of
bytes received/available.

0x2 is just right.

Move struct scsi_read_cap_data and struct scsi_read_cap_data_16 to
scsi_all.h.

Add scsi_read_cap_10() and scsi_read_cap_16() functions to
scsi_base.c, i.e. move logic to do actual READ_CAPACITY commands out
of sd_read_cap() and sd_read_cap_16().

This will allow the READ_CAPACITY code to be reused by cd(4).

Return -1 for errors where the error code is just discarded, reducing
ENOMEM, ENXIO, EIO uses.

No intentional functional change.

Refactor probing logic to mirror detach logic. i.e. put smarts in
scsi_probe() and make scsi_probe_bus(), scsi_probe_target() and
scsi_probe_lun() simple wrappers around scsi_probe().

Abstract the determination of which luns to probe into a separate
function. Thus eliminating the need to remove/add lun 0 link while
probing devices modern enough to support REPORTLUNS. Which means the
lun 0 link is no longer in different positions in the scsi_link list
for such devices compared to older devices which are blindly probed
until an invalid LUN is encountered.

Shrink struct scsi_sense_data and thus the sense member of scsi_xfer,
to 18 bytes by removing the extra_bytes field. sbic.c was the only
consumer, and that was in a DEBUG message.

18 bytes is the minimum length mandated by the SCSI spec. Anything
more is vendor/device specific information.

This fixes a usb key that yuo@ had, and probably others.

Any device that decides to pay attention to extra sense data must
allocate its own space.

the SAT spec from t10.org defines messages for tunnelling ATA commands over
SCSI when you're talking to a scsi to ata translation layer (satl). this
implements the ata command ioctl handler in scsi_ioctl.c that wraps the
ata command requests up in these scsi commands and then issues them against
the hardware. this cuts atascsi over to interpreting these scsi commands
rather than the ioctls directly.

this should allow mpi users (with a relatively recent firmware) to use
atactl against their SATA disks. i cant test cos my mpi(4) parts are too
old to either support these scsi commands or too old to take recent
firmwares.
