KVM: Interrupt mask notifiers for ioapic
Allow clients to request notifications when the guest masks or unmasks a particular irq line. This complements irq ack notifications, as the guest will not ack an irq line that is masked. Currently implemented for the ioapic only. Signed-off-by: Avi Kivity <avi@redhat.com>
