This patch introduces support for event suppression. This is done by have a two areas: device area and driver area. One side could then try to disable or enable (delayed) notification from other side by using a boolean hint or event index interface in the areas. For more information, please refer Virtio spec.

We need to set log when updating flags of used ring, otherwise they may be missed after migration. A helper was introduced to write used_flags back to guest memory and update the log if necessary.
