  fftools/ffprobe: Make pix_fmt output bitexact
  
  It is currently not due to endianness. This forced to add
  workarounds with sed in fate/mxf.mak (which are removed
  in this commit).
  This is supposed to fix the enhanced-flv-hevc-hdr10 test
  on big endian systems.

  avcodec/ffv1: Implement 2D RLE for remap
  
  ATM this performs as well or better as any other algorithm tried.
  Its simple for the decoder.
  On the encoder side complexity depends on how parameters are
  chosen. But with a fixed mul_count of 1 and basic heuristic
  it performs as well as any more complex choice i tried so far.
  
  The encoder code here is flexible and allows mul_count > 1
  and also can easily be used to exactly test various parameters.
  
  With mul_count=512 we can gain another 6% in remap table size
  for fixed point in float data. (this is not implemented in this
  patch though)
