4d4098da00 lavfi: drop planar/packed negotiation support
The planar/packed switch and the packing_formats list is no longer
required, since the planar/packed information is now stored in the sample
format enum.

This is technically a major API break, possibly it should be not too
painful as we marked the audio filtering API as unstable.

fd2cd64fc9 avfiltergraph: fix format selection.
The old code had two bugs:

For audio filters, the format was not set.

For video filters, if several links reference the same format list,
the same format must be selected in the end. This is done by
setting formats->format_count to 1: the other links sharing
the reference will therefore have only one choice.
If the heuristic does not pick the first format, the selected format
must also be moved to the first position.

63736fe48c avfiltergraph: try to reduce format conversions in filters.
Current code, with a filterchain such as
(input - yuv411) -> (scale - any) -> (sink - any)
will result in yuv420 being chosen for the second link, which is clearly
not right.

This commit attempts to improve in the following way:
repeat until convergence:
  loop over all filters
    find input link with exactly one format
    force this format on all output links of the same type (if possible)

42655b24c2 avfiltergraph: avoid harmful auto audio conversions.
With the current code, an automatically inserted aconvert necessary
for format change would usually convert to mono for no good reason.

The new code will not avoid all conversions, but at least will keep
them among the layouts common to both filters.

4fcbb2af33 Prefix with "ff_" the functions:
ff_avfilter_graph_check_validity()
ff_avfilter_graph_config_links()
ff_avfilter_graph_config_formats()

and move their declaration to internal.h. These functions are never
used in application code, so it is better to consider them internal
functions, this can be changed later if necessary. Simplify API.

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.
