f4d5d7e8de avcodec/mpeg2dec: Fix motion vector rounding for chroma components 
In 16x8 motion compensation, for lower 16x8 region, the input to mpeg_motion() for motion_y was "motion_y + 16", which causes wrong rounding. For 4:2:0, chroma scaling for y is dividing by two and rounding toward zero. When motion_y < 0 and motion_y + 16 > 0, the rounding direction of "motion_y" and "motion_y + 16" is different and rounding "motion_y + 16" would be incorrect.

We should input "motion_y" as is to round correctly. I add "is_16x8" flag to do that.

cb97400f93 Revert "cmdutils: make use of new iteration APIs" 
This reverts commit cdc78058c7.

It introduced several issues in the command line tools, and it's
implementing a new API that may still see some changes.
Revert for the time being until the state of the API is defined.
