Add the new atpic(4) driver for the 8259A master and slave PICs.  By
default we provide 16 interrupt sources for IRQs 0 through 15.  However,
if the I/O APIC driver has already registered sources for any of those IRQs
then we will silently fail to register our own source for that IRQ.

Note that i386/isa/icu.h is now specific to the 8259A and no longer
contains any info relevant to APICs.  Also note that fast interrupts no
longer use a separate entry point.  Instead, both fast and threaded
interrupts share the same entry point which merely looks up the appropriate
source and passes control to intr_execute_handlers().
