024db24912 mpegvideo: allocate edges when encoding. 
Allocating edges will be removed from generic code, so the encoder must
handle this explicitly.

9ecabd7892 h264: reset num_reorder_frames if it is invalid 
An invalid VUI is not considered a fatal error, so the SPS containing it
may still be used. Leaving an invalid value of num_reorder_frames there
can result in writing over the bounds of H264Context.delayed_pic.

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.
