MFC IPI panic fix done by Stephan Uphoff:
	sys/i386/i386/apic_vector.s	1.101 -> 1.102
	sys/i386/i386/mp_machdep.c	1.241 -> 1.243
	sys/i386/include/apicvar.h	1.8 -> 1.9
	sys/i386/include/smp.h		1.78 -> 1.79

To quote the original commit message:
	Avoid more than two pending IPI interrupt vectors per local APIC
	as this may cause deadlocks.

	This should fix kern/72123.

This commit is a combination of Stephan's original one and John's style
fix on mp_machdep.c.  I have tested the patch on various SMP boxes running
RELENG_5_3 (4*P3 Xeon, 2*P4 w/HTT, 2*P4 Xeon configurations) under heavy
load for a couple of weeks, so commit on behalf of Stephan when he is
on vacation.

RELENG_5_3 candidate after settle time.
