    Most of the changes are just trivial are just trivial replacements of
    fields from MpegEncContext with equivalent fields in H264Context.
    Everything in h264* other than h264.c are those trivial changes.
    
    The nontrivial parts are:
    1) extracting a simplified version of the frame management code from
       mpegvideo.c. We don't need last/next_picture anymore, since h264 uses
       its own more complex system already and those were set only to appease
       the mpegvideo parts.
    2) some tables that need to be allocated/freed in appropriate places.
    3) hwaccels -- mostly trivial replacements.
       for dxva, the draw_horiz_band() call is moved from
       ff_dxva2_common_end_frame() to per-codec end_frame() callbacks,
       because it's now different for h264 and MpegEncContext-based
       decoders.
    4) svq3 -- it does not use h264 complex reference system, so I just
       added some very simplistic frame management instead and dropped the
       use of ff_h264_frame_start(). Because of this I also had to move some
       initialization code to svq3.
