Add a new <ioapic> element with a driver attribute.
Possible values are qemu and kvm. With 'qemu', the I/O
APIC can be put in the userspace even for KVM domains.

Please make sure that only x86 guests can use the <ioapic/>

Also I didn't check whether this is the case already, but
the feature should be advertised the same way <apic/> is,
and in particular it should show up in the capabilities XML.
