virtio-bus: common ioeventfd infrastructure
Introduce a set of ioeventfd callbacks on the virtio-bus level that can be implemented by the individual transports. At the virtio-bus level, do common handling for host notifiers (which is actually most of it). Two things of note: - When setting the host notifier, we only switch from/to the generic ioeventfd handler. This fixes a latent bug where we had no ioeventfd assigned for a certain window. - We always iterate over all possible virtio queues, even though ccw (currently) has a lower limit. It does not really matter here.
