[PATCH v5 03/17] Extend QMP command query-cpus to return accelerator id and model name

[Michael Mueller <mimu@xxxxxxxxxxxxxxxxxx>]

The QMP command query-cpus now additionally displays a model name and
the backing accelerator. Both are omitted if the model name is not
initialized.

  request:
    { "execute" : "query-cpus" }

  answer:
    { { "current": true,
        "CPU": 0,
        "model": "2827-ga2",
        "halted": false,
        "accel": "kvm",
        "thread_id": 31917
      }, ... }
