598ce4ab4f h264: call av_frame_unref() instead of avcodec_get_frame_defaults().
This is a temporary workaround to allow deprecating
avcodec_get_frame_defaults(). The proper solution will be using a
properly allocated AVFrame in Picture.

9e5ef1c5c3 h264: Do not treat the initial frame special in handling of frame gaps
The not handling of frame gaps has lead to the lack of a dummy reference
frame, which has lead to the failure of decode_slice_header() which has
lead to one SEI recovery message being skiped which had introduced a
slightly suboptimal recovery point for at least 1 h264 file compared to
JM.
