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.

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

needed.

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().

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.
