similar to: [PATCH] drm/virtio: Add window server support

This is to allow clients running within VMs to be able to communicate with a compositor in the host. Clients will use the communication protocol that the compositor supports, and virtio-gpu will assist with making buffers available in both sides, and copying content as needed. It is expected that a service in the guest will act as a proxy, interacting with virtio-gpu to support unmodified

Hi, this work is based on the virtio_wl driver in the ChromeOS kernel by Zach Reizner, currently at: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/virtio/virtio_wl.c There's one feature missing currently, which is letting clients write directly to the host part of a resource, so the extra copy in TRANSFER_TO_HOST isn't needed.

Since commit "9fdd90c0f4 drm/virtio: add virtio_gpu_alloc_fence()" fences are not allocated any more by virtio_gpu_fence_emit(). So there is no need to pass down a reference to the fence pointer, a plain pointer is enough now. Convert virtio_gpu_fence_emit() and callers.
