Add support to libvirt for the 'blob' option for virtio video devices in qemu.
Also do a little preparatory refactoring of the video device xml parsing code.

I sent this series out a couple months ago but didn't get any review. Sending
out again after rebasing to current master branch.

changes in v3:
 - rebased to latest master

Changes in v2:
 - Added some basic documentation
 - add a qemu capability
 - Make sure that the /dev/udmabuf device is accessible to qemu (cgroups, etc)

Jonathon Jongsma (6):
  conf: Refactor video model parsing
  conf: switch to virXMLProp* functions
  conf: use enum variable for video type
  conf: add support for 'blob' in virtio video device
  qemu: Add capability for virtio-gpu.blob
  qemu: Implement 'blob' support for virtio gpu
