thorpej f113ac70dd Add a "max_target" member to struct scsi_link, which is filled in by
host adapter drivers, indicating the highest SCSI target they can
address.  Use this value to dynamically allocate data structures, rather
than hard-coding 8 targets.

These changes allow targets > 7 to be addressed on wide SCSI busses.

Fixes PRs #1674 and #2892.

matthias c53ad1988a * At least the Teac FC-1 Shugart-SCSI bridgeboard does motor on/off
management by itself. But when it gets a start unit request, it keeps
the floppy motor running all the time. This adds code for dealing with
yet another quirk (SDEV_NOSTARTUNIT) that prevents sd.c from sending
start unit requests. A entry for the Teac FC-1 is added to the quirk
table.

thorpej f60341a382 Store the SCSI version in the scsi_link, and set the LUN in the CDB
if the version is <= SCSI-2.  This should help some older SCSI
devices that previously needed the "NOLUNS" quirk.  While this is
not strictly necessary on SCSI-2 devices, the spec allows it,
so we set it for SCSI-2 devices "just in case".  See section 7.2.2 of
Draft X3T9.2 Rev 10L for details.

cgd 11ec3588ad (1) add a 'channel' field to scsi_link.
(2) in scsibusmatch, match channel as appropriate.
(3) add a scsiprint() function, to do the "scsibus at..."
    and channel (if not SCSI_CHANNEL_ONLY_ONE) printing,
    i.e. the common functionality that all SCSI drivers currently
    should be doing.

christos 7e1c82f6f4 - Apply PR/2535: Add support for flex scsi disks.
- Add a quirk called SCSI_NOMODESENSE for drives like the iomega jaz,
  that don't support mode sense.

thorpej 8068d9eeb2 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.

cgd f60db5f02a add a SDEV_FORCELUNS flag, as suggested by Jason Thorpe, to force
the SCSI code to look for LUNs on prehistoric (pre-SCSI 1) drives &
controllers, where normally it would not.

mycroft b76a328caa Redo the `wait for spin up' code. The Mach 3 method clearly doesn't work.
Also, rearrange the first open sequences a bit; SDEV_OPEN is no longer magic.

deraadt a0bcb17e60 support for making dev->id_alive be set, this is for iostat to
