Support DRM out-fences by creating a sync_file with a fence for each CRTC that sets the OUT_FENCE_PTR property.
I still maintain the out fence should also be per fb (well, per plane since we can't add it to fbs). Otherwise it's not going to be at all useful if you do fps>vrefresh and don't include the same set of planes in every atomic ioctl, eg. if you only ever include ones that are somehow dirty.
How would the kernel signal these dirty planes then? Right now we signal at the vblank.
