Trailing bits are likely to be non-zero if the NAL unit is truncated.
Clearing the bits make overreads of the bitstream less likely in this
case. Fixes playback of
http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 which
has a forbidden byte sequence of 0x00 0x00 0x00 in it SPS.
Start code emulation prevention is only required in Annex B bytestream
packed NAL units. For other coding formats the size is already known.
Looking for a start code prefix can result in false positives like in
http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4
which has a false positive in the SPS.
The keyframe after a POC reset may not be the first to be returned to
the user. Therefore, don't reset the expected next POC once we return
a keyframe to the user, but once we know that the next frame in the
return-queue is a keyframe.

A new field, AVCodecContext.internal is used to hold a new struct
AVCodecInternal, which has private fields that are not codec-specific and are
used by general libavcodec functions.
Moved internal_buffer, internal_buffer_count, and is_copy.

avctx->width/height remain right/bottom cropped as previous behaviour.
Hardware decoders need to know the uncropped data to allocate surfaces
of correct height. Some hardware is picky and fails to decoder properly
if a surface larger than needed is used during decode, so just aligning
up is not enough.

This fix is not ideal as it still limits the multithreading on field pictures
to the 2nd field only.
Ill try to fix it properly to allow both fields to decode concurrently but this
needs more work.
This bug exists since and was caused by:
commit ea6331f8bb
Author: Ronald S. Bultje <rsbultje@gmail.com>
Date: Mon Jun 20 10:24:33 2011 -0400
h264-mt: fix deadlock in packets with multiple slices (e.g. MP4).
The ff_h264_decode_extradata routine now checks for the buffer size
and pointer internally. This makes it possible to remove the external
checks in ff_h264_decode_init.
In decode_frame there was a size check missing because the buffer
gets tested prior to the invocation of ff_h264_decode_extradata().
