    cinepakenc : add option handling for flexibility

    Now it is possible to adjust compression speed vs R/D when needed
    
and also skip vintage player compatibility at will.

    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.

    cinepakenc : fixes and improvements

    version 2013-02-08 Rl

    - fixes/optimization in multistrip encoding and codebook size choice,
    
  quality/bitrate is now better than that of the binary proprietary encoder
    

    version 2013-02-12 Rl

    - separated codebook training sets, avoided the transfer of wasted bytes,
    
  which yields both better quality and smaller files

    - now using the correct colorspace (TODO : move conversion to libswscale)
    

    version 2013-02-14 Rl "Valentine’s Day" version :

    - made strip division more robust

    - minimized bruteforcing the number of strips,
    
  (costs some R/D but speeds up compession a lot), the heuristic
    
  assumption is that score as a function of the number of strips has
    
  one wide minimum which moves slowly, of course not fully true

    - simplified codebook generation,
    
  the old code was meant for other optimizations than we actually do

    - optimized the codebook generation / error estimation for MODE_MC
    

    version 2013-04-28 Rl

    - bugfixed codebook optimization logic
    

    version 2014-01-20 Rl

    - made the encoder compatible with vintage decoders
    
  and added some yet unused code for possible future
    
  incremental codebook updates

    - fixed a small memory leak
    

    version 2014-01-21 Rl

    - believe it or not, now we get even smaller files, with better quality
    
  (which means I missed an optimization earlier :)
