Please evaluate these patches as being seperate from virtproxy.

Michael,

On a general note, while the protocol stuff probably should go into
QEMU, then I don't see the actual agent belonging in the QEMU tree. If
you put it all together, you are less likely other agents are willing to
adopt virtproxy.

Cheers,
