vc1: skip motion compensation when data for last picture is invalid
This commit is a noop. The crash can't be reproduced with ffmpeg.

Fixes two warnings:
libavformat/rtpdec.c:155:20: warning: return discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
libavformat/rtpdec.c:168:20: warning: return discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
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.

For B field pictures, the spec says,
> The prediction shall be made from the field of the same parity as the field being predicted.
I did it.

An index should never be equal to the count. Hence we must make sure
*ctts_index < ctts_count.

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.

If a subdemuxer has the updated metadata event flag set, the metadata is copied
to the corresponding stream. The flag is cleared on the subdemuxer and the
appropriate event flag is set on the stream.

Demuxing only. Muxing is disabled as altref frame handling is not
defined in the spec, and there's no way to know the presence of
such frames during stream initialization.
Based on a patch by Steven Liu.
