notifier: event notifier implementation
event notifiers are slightly generalized eventfd descriptors. Current
implementation depends on eventfd because vhost is the only user, and
vhost depends on eventfd anyway, but a stub is provided for non-eventfd
case.
We'll be able to further generalize this when another user comes along
and we see how to best do this.
