They are only implictly reset on keyframes, making it quite likely for an interframe to desync if a prior frame's header was corrupt or missing outright!

For coeff decode, we need to know whether the above block had non-zero coefficients.
This means for each macroblock, we need data for 4 luma blocks, 2 u blocks, 2 v blocks, and the luma dc block, for a total of 9 per macroblock. We keep the last row in top_nnz.
