  avformat/mov: don't use stream duration to calculate bitrate with fragmented input
  
  sc->data_size may contain the size of a single fragment after probing, and
  using it alongside the duration of the entire stream to calculate bitrate
  will result in a bogus small value.
  
  Before:
    Duration: 00:00:05.00, start: 0.000000, bitrate: 586 kb/s
    Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(progressive), 640x360 [SAR 1:1 DAR 16:9], 112 kb/s, 60 fps, 60 tbr, 15360 tbn (default)
  
  After:
    Duration: 00:00:05.00, start: 0.000000, bitrate: 586 kb/s
    Stream #0:0[0x1](und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(progressive), 640x360 [SAR 1:1 DAR 16:9], 561 kb/s, 60 fps, 60 tbr, 15360 tbn (default)

  avcodec/x86/vp3dsp_init: Set correct function pointer, fix crash
  
  Regression since fd172185580c1ccdcfb90bbfdb59fa806fad3117;
  triggered by vp4/KTkvw8dg1J8.avi in the FATE suite, but not
  when running fate as this code is not used when the bitexact
  flag is set.
  
  Bisecting done by ami_stuff, patch from user Mika Fischer
  in ticket #10027 (which this commit fixes).
