b881fbe9f7 pc: Generalize ISA IRQs to GSIs 
The ISA bus IRQ range is 0..15. What isa_irq_handler and IsaIrqState are
actually dealing with are the Global System Interrupts. Refactor the
code to clarify this.

0280b571c1 ioapic: Implement EOI handling for level-triggered IRQs 
Add the missing EOI broadcast from local APIC to the IOAPICs on
completion of level-triggered IRQs. This ensures that a still asserted
IRQ source properly re-triggers an APIC IRQ.
