struct scsipi_adapter; they were not used.
Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.
Inspired by PR #6090, from Matt Jacob.
(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.
second argument. The NuBus autoconfig code had to be reorganized as a
result of this, and looks much more like a directly-attached bus now.
These changes eliminate __BROKEN_INDIRECT_CONFIG.

single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.

a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
reject them for simple commands. Leo W. reports that this does
not work for some systems. It's better than what we have now,
though. From Paul Goyette <paul@pgoyette.bdt.com>.
MSG_REJECT_MESSAGE instead of MSG_ABORT when we get an extended message.
This allows a DEC drive to work when it attempts to negotiate synch.
transfers on us.
I added two new bitfields to ncr_softc. They flag which devices have
been selected, and which ones have failed to go to message out when
selected with ATN. If a target fails to go to message out the first
time it is selected, it goes into the latter bitfield. If it fails
thereafter, we treat it as we did before.
