The actual hwaccel code will need to access an internal context instead of avctx->hwaccel_context, so add a new DXVA_CONTEXT() macro, that will dispatch between the "old" external and the new internal context. Also, the new API requires a new D3D11 pixfmt, so all places which check for the pixfmt need to be adjusted. Introduce a ff_dxva2_is_d3d11() function, which does the check.
