a13a543797 Add a slice_dir parameter to avfilter_draw_slice().
Avoid the need to implement slice direction detection code, thus
reducing code duplication.

See the thread:
"[FFmpeg-devel] [PATCH] Add a slice_dir parameter to avfilter_start_frame()".

bd2837387c Document slice ordering assumption required by avfilter_draw_slice().
The assumption depends on the corresponding assumption done by
sws_scale() and by the scale filter.

86a60fa1ac Implement a new registration system for filters.
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.

da23d42476 Make avfilter_get_video_buffer() use
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.

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

0eb4ff9e37 Make avfilter_get_video_buffer() recursive.
When called on a link with a filter whose destination pad has not a
get_video_buffer callback defined, it will call
avfilter_get_video_buffer() on the first output link of the
destination filer, rather than use avfilter_default_get_buffer(), so
the video buffer can be allocated forward in the filterchain.

Also add the w and h parameters to avfilter_get_video_buffer(), as the
minimum width and height requested by each filter in the filterchain
may change, this allows for example a memcpy-less pad filter.

This change breaks API / ABI backward compatibility.

987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
