It was decoupled from QEMU own gl-blocking mechanism, but that difference isn't really helping. Instead, we can reuse QEMU gl-blocking and notify virtio_gpu_gl_flueshd() when unblocking (to unlock vhost-user-gpu). An extra block/unblock is added arount dpy_gl_update() so existing backends that don't block will have the flush event handled. It will also help when there are no backends associated.
