Pass the VM's UUID into the nwfilter subsystem
A preparatory patch for DHCP snooping where we want to be able to differentiate between a VM's interface using the tuple of <VM UUID, Interface MAC address>. We assume that MAC addresses could possibly be re-used between different networks (VLANs) thus do not only want to rely on the MAC address to identify an interface. At the current 'final destination' in virNWFilterInstantiate I am leaving the vmuuid parameter as ATTRIBUTE_UNUSED until the DHCP snooping patches arrive. (we may not post the DHCP snooping patches for 0.9.9, though) Mostly this is a pretty trivial patch. On the lowest layers, in lxc_driver and uml_conf, I am passing the virDomainDefPtr around until I am passing only the VM's uuid into the NWFilter calls.
