6fdbaa2b7f vp8: change mv_{min,max}.{x,y} type to int 
If one of the dimensions is larger than 8176, s->mb_width or
s->mb_height is larger than 511, leading to an int16_t overflow of
s->mv_max.{x,y}. This then causes av_clip to be called with amin > amax.

Changing the type to int avoids the overflow and has no negative
effect, because s->mv_max is only used in clamp_mv for clipping.
Since mv_max.{x,y} is positive and mv_min.{x,y} negative, av_clip can't
increase the absolute value. The input to av_clip is an int16_t, and
thus the output fits into int16_t as well.

For additional safety, s->mv_{min,max}.{x,y} are clipped to int16_t range
before use.

b18eac7ff2 vp9: change type of tile_size from unsigned to int64_t 
Otherwise the check 'tile_size < size' treats a negative size as
unsigned, causing the check to pass. This subsequently leads to

ed09bb3782 avcodec/apng: Dispose previous frame properly 
The spec specifies the dispose operation as how the current (i.e., currently
being rendered) frame should be disposed when the next frame is blended onto it

This is contrary to ffmpeg's current behaviour of interpreting the dispose
operation as how the previous (i.e., already rendered) frame should be disposed

This patch fixes ffmpeg's behaviour to match those of the spec, which involved
a rewrite of the blending function

Since decoder couldn't properly map 4 back channels, decoding failed

0289f81241 aac: Correctly map multichannel ADTS AAC with non-zero channel_config + PCE 
The decoder assigns channels using default channel configuration
for 5.1ch when it parses an ADTS frame header using consecutive
channel ids.

When a PCE comes, it reassigns channels using PCE configuration
using directly the ids provided. They can be arbitrary.

Always use consecutive channel ids to avoid decoding glitches due
spurious reconfigurations due the channel ids mismatch between the
two otherwise-identical channel maps.
