303841c92e 3c509 fixes to avoid adapter getting stuck in high traffic conditions. 
I don't particularly like the fixes, but at least now the 3c509 never
gets stuck. On the other hand, performance still sucks in some cases.

5ac2484d95 * 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.

d5f99262a9 Since npxdna() and npxsave() are only ever called at spl0 now, we can get rid 
of all the overhead of frobbing the IDT, and just use a simple flag to tell
npxintr() to ignore interrupts.  This allows lots of code reduction.
Also, update some comments and add some DIAGNOSTIC code to detect is these
assumptions ever become wrong.

5cf38ebdb4 The case of curproc == 0 `can't happen' unless we're in the idle loop, so 
allow it to panic by way of a reference to 0 in other cases.  Explicitly test
for p == 0 in the specific cases where it's needed, and only calculate pcb if
needed.

9a84611b06 Move the spl0() from the idle loop to the top of cpu_switch(). (This also 
avoids needing to call spllower() below.)  Set curproc immediately after
removing the new process for the run queue, before allowing interrupts again,
for the benefit of schedcpu().

205d425f2f As pointed out by Bruce, splsoftclock() needs to process pending interrupts 
when lowering the priority.  Do this by simply calling splx().  For the
benefit of NFS (for now), modify splx() to return a value so that
splsoftclock() does.  This work is optimized out for every use of splx()
that ignores the value, so it only affects relevant code.
Also, clean up this file a little.

* 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.
