7f0e81db3c h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 
Higher modes are not allowed for 16x16/chroma, which is what this
function is used for. Otherwise this function would return 0 (vertical
prediction) for invalid higher modes, which could result in invalid
reads.

d1b3fabe69 h264: reset first_field if frame_start() fails for missing refs 
In this case we may not have a current frame, while first_field being
set implies we do.

Fixes invalid reads.

b53aab1a58 libavcodec/huffyuv: >8 bit support 
This adds only yuv420p10, others are trivial to add after this commit
and will be added in a subsequent commit.
Currently the implementation is not optimized, optimizations will be
added later
