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.
