so we can merge io_apic_32.c and io_apic_64.c
v2: Use cpu_online_map as target cpus for bigsmp, just like 64-bit is doing.
Also remove some unused TARGET_CPUS macro.
v3: need to check if desc is null in smp_irq_move_cleanup
also migration needs to reset vector too, so copy __target_IO_APIC_irq
from 64bit.
(the duplication will go away once the two files are unified.)

but actually irq still needs to be less than NR_IRQS, because
interrupt[NR_IRQS] in entry.S.
need to enable per_cpu vector...

also add first_free_entry and pin_map_size, which were NR_IRQS derived
constants.

64bit mode APIC interrupt handlers are set within irqinit_64.c.
Lets do tha same for 32bit mode which would help in furter code merging.

The leftovers of the i8259 unification have nothing to do with i8259
at all. They contain interrupt init code and the i8259_xx name is just
misleading now.
Rename them to initirq_32/64.c
