    lavu: add new D3D11 pixfmt and hwcontext · 3303511f

    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 fff90422.
