Stefano Sabatini cf5fe8ec9e Make avfilter_config_links() use the timebase of the first input link
of a filter for setting the output timebase, if there is such a link,
rather than always use AV_TIME_BASE_Q.

This fixes configuration for all the filters which do not use the
default config_props for the output link, and do not set explicitely
the timebase.

Stefano Sabatini 5a9dd3de63 Make avfilter_start_frame() invoke avfilter_get_video_buffer() on the
link rather than avfilter_default_get_video_buffer().

This is required as the buffer requested may be greater than the
buffer allocated locally by avfilter_default_get_video_buffer(), for
example if in filterchain there is a pad filter (like in "fifo,pad").

In that case the pad filter will try to write beyond the data of the
allocated buffer, resulting in a crash.

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);

to be used for other purposes and this interface may change in the
future, thus it is not documented.
