`void *' arg. Fixed or hid most of the resulting type mismatches.
Handlers can now be updated locally (except for reworking their
global declarations in isa_device.h).
a test of the irq number, and made failure of this test non-fatal.
Removed related unused complications for the APIC_IO case. Removed the
no-test3 flag.
Deverbosified the failure messages for the other tests. Removed the
per-port verbose flag - just use the general verbose flag.
interrupts are masked, and EOI is sent iff the corresponding ISR bit
is set in the local apic. If the CPU cannot obtain the interrupt
service lock (currently the global kernel lock) the interrupt is
forwarded to the CPU holding that lock.
Clock interrupts now have higher priority than other slow interrupts.
the signal handling latency for cpu-bound processes that performs very
few system calls.
The IPI for forcing an additional software trap is no longer dependent upon
BETTER_CLOCK being defined.
Wrappered and enabled by the define BETTER_CLOCK (on by default in smpyests.h)
apic_vector.s also contains a small change I (smp) made to eliminate
the double level INT problem. It seems stable, but I haven't the tools
in place to prove it fixes the problem.

- added Xcpustop IPI code to support stop_cpus()/restart_cpus().
it is off by default, enable via smptests.h:TEST_CPUSTOP
intr_machdep.h:
- moved +ICULEN to lower level.
- added entry for Xcpustop.
