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.

This way it is easier to reference them in other structures, for
example in the pending AVFilterSamplesRef struct.

These fields are never used, and they do not seem to belong to
AVFilterBuffer anymore, now that it is now a media-independent
structure and these fields are video-related.

The struct is going to be used for audio data as well, so the new name
is less misleading.

byte position information, as stored in the pkt.pos, through the
filterchain.
Note that the pos field is added *non* at the end of the
AVFilterPicRef struct, thus breaking ABI compatibility, which is
allowed as the API is still considered non-stable.

AVFilter.query_formats doxy.
The doxy expresses what a function does, not what it should do.

*avff, so that an AVFilterFormats struct is created and returned by
the function if *avff is NULL.
Make the function use more convenient.

Avoid the need to implement slice direction detection code, thus
reducing code duplication.

The assumption depends on the corresponding assumption done by
sws_scale() and by the scale filter.

Create a new static array containing pointers to the AVFilter
definitions, so that the non-constant next filter in the AVFilter
struct is not anymore required and the AVFilter definitions may be
stored in shareable memory.
Also change the signature for avfilter_register(), make it return an
int since it may fail if there is not enough space in the static array
for the registered filters.

avfilter_default_get_video_buffer() if the get_video_buffer() callback
is not defined in a filter.
Libavfilter filters author have to explicitely define the
get_video_buffer() callback if they want the buffer to be requested to
the filter following in the filterchain.

"[FFmpeg-devel] [PATCH] Make avfilter_get_video_buffer() use
default_get_video_buffer if callback not defined".
