Subject: [PATCH RFC 0/1] Support virtio objects in virtio-video driver

This implements a feature in virtio-video driver to use exported virtio
objects as video buffers. So, the users will be able to use resources
allocated by other virtio devices such as virtio-gpu.

The virtio protocol for this feature is proposed by [1].

This commit depends on the following unmerged patches:
* Virtio-video driver patch [2]
* Patch series for virtio cross-device resources [3]
* ChromeOS's local patch to use data_offset for offset of multiplanar
  format [4]
