> VA-API (Video Acceleration API) user mode driver for Intel GEN
> Graphics family
>
> VA-API is an open-source library and API specification, which provides
> access to graphics hardware acceleration capabilities for video
> processing. It consists of a main library and driver-specific
> acceleration backends for each supported hardware vendor.
>
> The current video driver backend provides a bridge to the GEN GPUs
> through the packaging of buffers and commands to be sent to the i915
> driver for exercising both hardware and shader functionality for video
> decode, encode, and processing.

FFmpeg failed to build with NASM, I wanted to try Yasm, but in the end
it worked fine with a newer NASM. Add the update anyway. But NASM seems
to be under more active development.

This adds the function `__vaDriverInit_1_3` to the drivers.

Tested on *keineahnung* (Intel) and *inbetweenmove* (AMDGPU).

Currently, only VDPAU is supported. But we want VA-API to be supported
as well.
