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.

Fixes breakage with --disable-muxers as it was originally limited
to the muxer, and not the demuxer.

An index should never be equal to the count. Hence we must make sure

This reverts commit cdc78058.

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.
