bdab614be8 Generalize pixel format enum fields to int formats.
This is needed to make the libavfilter framework work with audio
filters.

In particular add a type field to AVFilterLink, change the field types:
enum PixelFormat format   -> int format   in AVFilterBuffer
enum PixelFormat *formats -> int *formats in AVFilterFormats
enum PixelFormat *format  -> int format   in AVFilterLink

and change the function signatures:
AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
AVFilterFormats *avfilter_make_format_list(const int *fmts);

int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
int avfilter_add_format(AVFilterFormats **avff, int fmt);

AVFilterFormats *avfilter_all_colorspaces(void); ->
AVFilterFormats *avfilter_all_formats(enum AVMediaType type);

This change breaks libavfilter API/ABI.

c1d662fd88 Change avfilter_add_colorspace() to make it accept **avff rather than
*avff, so that an AVFilterFormats struct is created and returned by
the function if *avff is NULL.

Make the function use more convenient.

5ff84183de Make avfilter_all_colorspaces() add to the returned list of pixel
formats only the non-HW-accelerated formats, for which there is no
sense in filtering.

9abba21ad3 Cosmetics: prefer "pix_fmts" over "pix_fmt" for the name of the
argument of avfilter_make_format_list(), as the argument represents a
list of elements.

f6a1fa850a Implement avfilter_make_format_list2(), which is going to replace
avfilter_make_format_list().
