That field will be deprecated and the value that is written there is not
particularly useful.

Also, stop using AVCodecContext.codec_name as fallback, since it will be
deprecated.

Changes the result of the lavf-asf test (and its associated seektest),
since 'msmpeg4v3' gets written instead of just 'msmpeg4'.

That field is undocumented, of dubious use, and will be deprecated.

Stop using the undocumented to-be-deprecated AVCodecContext.codec_name
field.

The addition of reference-counted frames makes it pointless.

Old Intel GPUs expect the reference frame index to the actual surface,
instead of the index into RefFrameList as specified by the spec.

This workaround should be set when using one of the "ClearVideo" decoder
devices.

The latest H.264 DXVA specification states that the index in this
structure should refer to a valid entry in the RefFrameList of the picture
parameter structure, and not to the actual surface index.

Fixes H.264 DXVA2 decoding on recent Intel GPUs (tested on Sandy and Ivy)

If framerate estimation is enabled, it makes sense to always apply it,
instead of limiting it to a few specific cases.

This caused mpv (and possibly others) to fallback to software decoding after
seeking a VC1 stream.
