Spice server needs to know about the vm state in order to prevent

Why this new hook?
qemu already notifies spice-server using QXLWorker start/stop callbacks.
It notifies the QXLWorker, and it goes to the display_channel. Spice api
changes anyway, by adding spice_server_set_seamless_migration, and as
other channels need this notification as well, it would be nicer to
explicitly notify the server about the vm start/stop and not abuse the
QXLWorker notification. Another option would have been to add notifier
for SpiceCharDeviceInterface as well, and then to any other new
interface that will require it.
