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.)

smp.h internal has include, so need to include that at first
when genericarch use them need to have different apicdef.h

... so it could fall back to normal numa and we'd reduce the impact of the
NUMAQ subarch.
NUMAQ depends on GENERICARCH
also decouple genericarch numa from acpi.
also make it fall back to bigsmp if apicid > 8.

a multi-socket test-system with 3 or 4 ioapics, when 4 dualcore cpus or
2 quadcore cpus installed, needs to switch to bigsmp or physflat.
CPU apic id is [4,11] instead of [0,7], and we need to check max apic
id instead of cpu numbers.
also add check for 32 bit when acpi is not compiled in or acpi=off.
