s390_flic_init() is a helper to create and realize either "s390-flic-kvm" or "s390-flic-qemu". When qdev_init() fails, it complains to stderr and succeeds. Except it can't actually fail, because the "s390-flic-qemu" is a dummy without a realize method, and "s390-flic-kvm"'s realize can't fail, even when the kernel device is really unavailable. Odd. Replace qdev_init() by qdev_init_nofail() to make "can't fail" locally obvious, and get rid of the unreachable error reporting.

Make use of the new s390 adapter irq routing support to enable real in-kernel irqfds for virtio-ccw with adapter interrupts. Note that s390 doesn't provide the common KVM_CAP_IRQCHIP capability, but rather needs KVM_CAP_S390_IRQCHIP to be enabled. This is to ensure backward compatibility.

Introduce a common parent class for both cases, where kvm and non-kvm can hook up callbacks. This will be used by follow-on patches for adapter registration and mapping. We now always have a flic, regardless of whether we use kvm; the non-kvm implementation just doesn't do anything.

S390 can also use async page faults, to enhance guest scheduling. In case of live migration we want to disable the feature and let all pending request finish.
