replay: notify CPU on event
This patch enables vCPU notification to wake it up when new async event comes in replay mode. The motivation of this patch is the following. Consider recorded block async event. It is saved into the log with one of the checkpoints. This checkpoint may be passed in vCPU loop. In replay mode when this async event is read from the log, and block thread task is not finished yet, vCPU thread goes to sleep. That is why this patch adds waking up the vCPU to process this finished event.
