wm4 3303511f33 lavu: add new D3D11 pixfmt and hwcontext
To be used with the new d3d11 hwaccel decode API.

With the new hwaccel API, we don't want surfaces to depend on the
decoder (other than the required dimension and format). The old D3D11VA
pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the
decoder configuration, and thus is incompatible with the new hwaccel
API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D
and an index. It's simpler and compatible with the new hwaccel API.

The introduced hwcontext supports only the new pixfmt.

Frame upload code untested.

Significantly based on work by Steve Lhomme <robux4@gmail.com>, but with
heavy changes/rewrites.

Merges Libav commit fff90422d1.

* The FFmpeg libraries follow a versioning sheme very similar to
* Semantic Versioning (http://semver.org/)
* The difference is that the component called PATCH is called MICRO in FFmpeg
* and its value is reset to 100 instead of 0 to keep it above or equal to 100.
* Also we do not increase MICRO for every bugfix or change in git master.
*
* Prior to FFmpeg 3.2 point releases did not change any lib version number to
* avoid aliassing different git master checkouts.
* Starting with FFmpeg 3.2, the released library versions will occupy
* a separate MAJOR.MINOR that is not used on the master development branch.
* That is if we branch a release of master 55.10.123 we will bump to 55.11.100
* for the release and master will continue at 55.12.100 after it. Each new
* point release will then bump the MICRO improving the usefulness of the lib
* versions.
