This patch added vm_event support in command monitor, so that vm_event can be sent to a client (e.g., Libvirt) through the monitor. As the command monitor works in socket server mode, the vm_event sending process is designed in this way: 1. If a client wishes to receive vm_event, it issues a REGISTER_VM_EVENT_CLIENT command to the monitor. 2. Command monitor then handles the REGISTER_VM_EVENT_CLIENT command. If it is legitimate, the client is registered as as vm_event receiver. The command monitor then send a ACK to the client, and keeps the socket connection. 3. When a vm_event is generated, the command monitor send it out through the socket connection. 4. Only one event client is allowed. 5. The registration is cancelled on socket disconnection.
