This has been cargo culted from mpegvideo and serves no useful purpose.
It will be initialize correctly in h264_field_start()

The name is misleading, this function does a lot more than just flushing
the DPB.

It represents the relationship between them more naturally and will be
useful in the following commits.

Allows significantly more frames in fate-h264-attachment-631 to be
decoded.

Those SEIs refer to the currently active SPS. However, since the SEI
NALUs precede the coded picture data in the bitstream, the active SPS is
in general not known when we are decoding the SEI.

Therefore, store the content of the picture timing SEIs and actually
parse it when the active SPS is known.
