7d9dc4013e virtio-devices: Introduce EpollHelper
This is a helper for implementing the worker thread for virtio devices
and in particular handles special behaviour for pause and kill events.

The device specific event handling (for the queues themselves) is
delegated to a method invoked on a new EpollHelperHandler trait. This
method is passed the event as well as the EpollHelper so that it can
operate on the handler in order to manage events itself (required for
virtio-net.)

Now set_gsi_routes, which is part of the interrupt module, is only

This further splits hypervisor specific code from hypervisor agnostic
code.
