The only awkward bit is that we want to connect the savevm state to a 
qdev device.  Ideally, each qdev device would have a single table of state.

With vmstate, we're moving away from the notion of blobs and 
serialization functions.  Instead, for a given qdev device, vmstate 
describes it's state in a table.
