In case someone else doesn't understand this commit message:
It seems these functions are all marked as av_cold in the .c files,
so stuff like grouping them together can be done without having av_cold
in the headers.
The idea then I guess is that any other optimizations the compiler might be
doing are unlikely to be relevant.
