Enabling this feature would eliminate data copies from the resource
object in the Guest to the shadow resource in Qemu. This patch series
however adds support only for Blobs of type
VIRTIO_GPU_BLOB_MEM_GUEST with property VIRTIO_GPU_BLOB_FLAG_USE_SHAREABLE.
Most of the patches in this series are a rebased, refactored and bugfixed
versions of Gerd Hoffmann's patches located here:
https://gitlab.freedesktop.org/virgl/qemu/-/commits/virtio-gpu-next
v2:
- Moved dpy_gl_update from set_scanout to resource_flush
- Dropped the modifier
- Rebase and other minor refactoring
