lavfi: remove unnecessary inclusion of libavcodec/avcodec.h in avfilter.h
libavfilter API was designed in order to be clarly distinguished from the
libavcodec API, including avcodec.h in avfilter.h is not going to help to
stick to this principle.
The inclusion of libavutil/audioconvert.h in many files was required
because avcodec.h includes audioconvert.h.
libavfilter/avcodec.h is where the lavc/lavfi interface should be
entirely placed.

lavfi: rename avfilter_all_* function names to avfilter_make_all_*
A function name should tell what the function does rather than what
the function returns. This also avoids possible conflicts
(e.g. between a function and a public list of all supported formats),
and clarifies the code.
Breaks audio API/ABI, add a backward compatibility layer for video
API/ABI.

lavfi: simplify signature for avfilter_get_audio_buffer() and friends
The additional parameters were never used and are complicating the
function interface. Also, they were inconsistent with the way the
video API works.
So this assumes that a requested samples buffer will have *always* the
format specified in the requested link.
This breaks audio filtering API and ABI.
