  dxva: support DXGI_FORMAT_420_OPAQUE decoding
  
  Some devices (some phones, apparently) will support only this opaque
  format. Of course this won't work with CLI, because copying data
  directly is not supported.
  
  Automatic frame allocation (setting AVCodecContext.hw_device_ctx) does
  not support this mode, even if it's the only supported mode. But since
  opaque surfaces are generally less useful, that's probably ok.

  hwcontext_d3d11va: allocate staging texture lazily
  
  Makes dealing with formats that can not be used for staging textures
  easier (DXGI_FORMAT_420_OPAQUE). It also saves memory if the staging
  texture is never needed, so this is a good thing.

  hwcontext_d3d11va: fix crash on frames_init failure
  
  It appears in this case, frames_ininit is called twice (once by
  av_hwframe_ctx_init(), and again by unreffing the frames ctx ref).

  dxva: fix some warnings
  
  Some existed since forever, some are new.
  
  The cast in get_surface() is silly, but unless we change the av_log
  function signature, or all callers of ff_dxva2_get_surface_index(), it's
  needed to remove the const warning.
