Well, this patch at least reduces the dependencies of the H.264 parser.
If in the future the functions used by the parser change, it will fail
to compile or link, so this will be caught eventually.
In any case h264.c is badly in need of splitting. The file is
monstrously huge and takes ages to compile. Why don't you go ahead and
split it into more sensible pieces? What I fear is that this will be
one more thing that gets added to an ever-growing todo list and never
