Bug 1510601 - Part 1. Move size increments into AnimationFrameBuffer::InsertInternal. r=tnikkel The size was originally incremented in AnimationFrameBuffer::Insert however if an animation was reset before we finished decoding, it would count some frames twice in the counter. Now we increment it inside InsertInternal, where AnimationFrameDiscardingQueue can make a more informed decision on whether the frame is a duplicate or not. Additionally we now fail explicitly when we insert more frames on subsequent decodes than the original decoders. This will help avoid getting out of sync with FrameAnimator.
