* Redo most of the message and phase state machines. Multiple pending
...
message outs should now work correctly (including retransmissions).
Multiple messages ins should be more efficient. Missing REQ after
reselection phase should now (correctly) cause a wait with ENREQINIT
set.
* Abstract out the reselection out sequence, and use it directly to
get sense info. (This is somewhat faster than the generic done/sched
sequence.)
* If there are no ACBs available, wait interruptibly for one.
* Leave the interrupt registers alone during message in/out; just
watch for phase change. Don't (incorrectly) reenable interrupts
during data in/out; defer that to aicintr().
* Handle command pointer per SCSI 2 spec.
* Other minor coding improvements.

...
* Forget all cached info when opening a new disc.
* If the disc is removed, flush the buffer queue rather than stalling it.
* Set the default label after getting the disc size, and fill in the info
for RAW_PART also.
* Change another use of the unit number to a softc pointer.
* Use a dkdevice to hold the label and open partition masks.
* Force the partition offset to 0 for RAW_PART, regardless of the label.
* Nuke MCDPHYS() and MCDREADRAW; they had a silly bug that caused the code
to not work, and they aren't useful anyway.
