Allow adding unconnected host drives by specifying if=none like it is
possible with -drive.  They can be put in use with drive attributes,
like this:

  drive_add dummy if=none,id=mydisk,file=/some/disk.img
  device_add virtio-blk-pci,drive=mydisk

which is the monitor aequivalent to these command line switches:

  -drive if=none,id=mydisk,file=/some/disk.img
  -device virtio-blk-pci,drive=mydisk
