In particular this fixes a crash in the rotate filter.

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

of the type 0xRRGBBAA parsed by av_parse_color(), using a simple int

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

The chroma values to use are supposed to be those of the input format,
not that of the output format, the latter case was causing crashes and
chroma issues.

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".
