b5eab66e9f Make avfilter_default_start_frame() request a buffer with the same
size of the output link of the destination filter, rather than of the
size of the input link.
In particular this fixes a crash in the rotate filter.

7d132c544b Use an unsigned int to contain all the color values of the expressions
of the type 0xRRGBBAA parsed by av_parse_color(), using a simple int
was resulting in unexpected results as the most significant bit was

a13a543797 Add a slice_dir parameter to avfilter_draw_slice().

reducing code duplication.

b37aa4de2d Use the correct chroma values for the data[] array used in
draw_slice().

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.

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".
