Add a model string to VLANClientState (Mark McLoughlin)

Don't lose track of what type/model a vlan client is so that we can
e.g. assign a global per-model id to clients.

The entire patch is basically a tedious excercise in making sure the
type/model string gets propagated down to qemu_new_vlan_client().
