[PATCH 4/5] qemu: Prefer -numa cpu over -numa node,cpus=

QEMU is trying to obsolete -numa node,cpus= because that uses ambiguous vCPU id to [socket, die, core, thread] mapping. The new form is: -numa cpu,node-id=N,socket-id=S,die-id=D,core-id=C,thread-id=T which is repeated for every vCPU and places it at [S, D, C, T] into guest NUMA node N. While in general this is magic mapping, we can deal with it. Firstly, with QEMU 2.7 or newer, libvirt ensures that if topology is given then maxvcpus must be sockets * dies * cores * threads (i.e. there are no 'holes'). Secondly, if no topology is given then libvirt itself places each vCPU into a different socket (basically, it fakes topology of: [maxvcpus, 1, 1, 1]) Thirdly, we can copy whatever QEMU is doing when mapping vCPUs onto topology, to make sure vCPUs don't start to move around. Note, migration from old to new cmd line works and therefore doesn't need any special handling.
