Pass the size of a resource when creating it so a backing can be kept in the other side.
Also pass the required offset to transfer commands.
This moves vtest closer to how virtio-gpu works, making it more useful for testing.
v2: - Use new messages for creation and transfers, as changing the behavior of the existing messages would be messy given that we don't want to break compatibility with older servers.
v3: - Use correct strides: The resource corresponding to the output display might have a differnt line stride then the IOVs, so when reading back to this resource take the resource stride and the the IOV stride into account.
v4: Fix transfer size calculation (Andrey Simiklit)
v5: Add comment about transfer size value in the PUT commend (Gurchetan). Add a comment about the size correction for transfers for reading and writing the resource. Fixing this by correctly evaluating the size upfront will need some work also on the virglrenderer side.
