Log Message:
MP: MP-safe and APIC-friendly spl*/splx() implementation.

Keep spl state as a level, rather than interrupt mask, since on
multiple APIC systems there may be more interrupt lines than can fit
in a single 32-bit word.

Interrupt levels are now compatible with the APIC priority scheme
(high order 4 bits of the IDT vector number).
