Experiments with adding preload instructions to this function yielded no
useful benefit, so these have not been included.

There is no point in having a separate file just for the instantiation
that provides the public functions.

There is no point in having this separate; it is not used as a template.

The functions are not used templatized.

The indirection makes no sense without multiple instantiation.

The indirection makes no sense without multiple instantiation.

This allows detemplatizing the bits that are not instantiated twice.

Multiple inclusion makes no sense as it is only used in the 8-bit case.

This allows for more elegant dependency and object declarations.

Store a variable per OutputStream instead of globals for
audio/video/extradata. This makes the code simpler and cleaner and fixes
2pass with multiple output streams.

Frame duplication now happens in vf_fps.
