      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, 
specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.

  Author: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>

      libxl: Add support for Virtio disk configuration
      
      This patch adds basic support for configuring and assisting virtio-mmio
      based virtio-disk backend (emulator) which is intended to run out of
      Qemu and could be run in any domain.
      Although the Virtio block device is quite different from traditional
      Xen PV block device (vbd) from the toolstack's point of view:
       - as the frontend is virtio-blk which is not a Xenbus driver, nothing
         written to Xenstore are fetched by the frontend currently ("vdev"
         is not passed to the frontend). But this might need to be revised
         in future, so frontend data might be written to Xenstore in order to
         support hotplugging virtio devices or passing the backend domain id
         on arch where the device-tree is not available.
       - the ring-ref/event-channel are not used for the backend<->frontend
         communication, the proposed IPC for Virtio is IOREQ/DM
      it is still a "block device" and ought to be integrated in existing
      "disk" handling. So, re-use (and adapt) "disk" parsing/configuration
      logic to deal with Virtio devices as well.
      
      For the immediate purpose and an ability to extend that support for
      other use-cases in future (Qemu, virtio-pci, etc) perform the following
      actions:
      - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect
        that in the configuration
      - Introduce new disk "specification" and "transport" fields to struct
        libxl_device_disk. Both are written to the Xenstore. The transport
        field is only used for the specification "virtio" and it assumes
        only "mmio" value for now.
      - Introduce new "specification" option with "xen" communication
        protocol being default value.
      - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current
        one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model
      
      An example of domain configuration for Virtio disk:
      disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, 
specification=virtio']
      
      Nothing has changed for default Xen disk configuration.
      
      Please note, this patch is not enough for virtio-disk to work
      on Xen (Arm), as for every Virtio device (including disk) we need
      to allocate Virtio MMIO params (IRQ and memory region) and pass
      them to the backend, also update Guest device-tree. The subsequent
      patch will add these missing bits. For the current patch,
      the default "irq" and "base" are just written to the Xenstore.
      This is not an ideal splitting, but this way we avoid breaking
      the bisectability.
