7cc4c9f32f lavfi/formats: avoid using AV_{PIX,SAMPLE}_FMT_NB 
Thatt hardcodes the number of formats into lavfi and will break when a
shared lavu is updated, adding new formats.

b74a1da49d lavfi: make formats API private on next bump.

43c7a01e98 lavfi: remove avfilter_default_* from public API on next bump. 
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

11b6a82412 lavfi: avfilter_merge_formats: handle case where inputs are same 
This fixes a double-free crash if lists are the same due to the two
merge_ref() calls at the end of the (useless) merging that happens.

0ec56d1144 lavfi: fix realloc size computation in avfilter_add_format() 
Replace sizeof((*avff)->formats)
with    sizeof(*(*avff)->formats)

as the size of the array element is given by the pointed element
rather than by its pointer.

In particular fix computation with the pending patch when
sizeof(int64_t) != sizeof(int64_t *).

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.

*avff, so that an AVFilterFormats struct is created and returned by
