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.

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.

9769a6a6f7 Various: 
* 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.

1. always do the stackgap_init()/CHECKALT first in syscalls that need it.
2. svr4_emul_find() uses malloc for the buf, does not use copyoutstr, but
   copyout().

Removed makesyscalls.sh; it was really old and we don't need a separate copy.
