Stefano Sabatini 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.

Stefano Sabatini 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.

Stefano Sabatini da23d42476 Make avfilter_get_video_buffer() use 
avfilter_default_get_video_buffer() if the get_video_buffer() callback

get_video_buffer() callback if they want the buffer to be requested to
the filter following in the filterchain.

Stefano Sabatini 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.

See the thread:
"[PATCH] Implement recusive avfilter_get_video_buffer()".

Stefano Sabatini 43d160fd00 Prefer "loglevel" over "logging level number or string" as argname of 
the loglevel command line option.

Make the loglevel option help message more clear, since the option
argument is shown as a single token, and make the whole message better
aligned with the other help messages.
