Include some example programs.

This allows implementing sources as well as filters.

Fixes a warning:
fftools/ffmpeg_opt.c:2057:21: warning: variable 'file_oformat' set but not used

This way it can be also used for other format.

SDL2 uses SDLCALL to specify a calling convention. On OS/2, it's defined
to `_System' which is similar to `_cdecl' but does not prepend '_'.

After all, without a header, a function is used without `_System'. And
linker will try to `_func' but fail because the function is `func' not
`_func'.

Using the new API gives the decoder the ability to produce
N frames per input packet. This is particularly useful with
mpeg2 decoders on some android devices, which automatically
deinterlace video and produce one frame per field.

Since the function used to be exposed for ffserver's sake, it was renamed
to the same name as a system's aton function which caused a collision.

This patch is taking care of https://trac.ffmpeg.org/ticket/6834.
It seems that one of the control operations that was available to get
the free decoders input slots was removed.

There is another control operation to retrieve the used slots. Given
that the input slot count is hardcoded to 4 in mpp at this point,
replacing the old control operation by the other one.

This was tested on Rockchip ROCK64.
