e72aa524d8 asrc_anullsrc: implement a request_frame callback for returning frames
This is mainly useful for filters (like the sox synth), which
overwrite the content of the passed data.

44ab77db9e asrc_anullsrc: extend syntax to make it accept a non positional list of arguments
The new syntax is more extensible and more user-friendly.

This breaks the previous syntax, should not be an issue as possibly
no-one is already using anullsrc.

37cc443c83 lavfi: add audio convert filter
Add aconvert filter to perform sample format, channel layout, and
packing format conversion.

The aconvert code depends on audio conversion code in libavcodec, so
this requires a dependency on libavcodec.

Based on previous work by S.N. Hemanth Meenakshisundaram and Mina Nagy
Zaki, performed for the GSoC 2010 and 2011.

4f7dfe12ea lavfi: rename vsink_buffer.c to sink_buffer.c, and vsink_buffer.h to buffersink.h
This is done in order to clarify the non-video-specific nature of the
buffersink code, as the result of the video/audio API unification of
the previous commit, and for improving overall consistency.

c4415f6ec9 lavfi: unify asink_buffer and vsink_buffer API
The new API is more generic (no distinction between audio/video for
pulling frames), and avoids code duplication.

A backward compatibility layer is kept for avoiding tools ABI breaks
(only for the video binary interface, audio interface was never used
in the tools).

61d55fda2b lavfi: tweak display aspect ratio variables in pad and scale filters
Previously, "dar" and "a" were documented like "input display aspect
ratio", but their actual value was "in_w/in_h".

In order to avoid to break scripts which rely on the "a" variable, the
patch keeps the same semantics but fixes the corresponding docs, and
fixes the semantics of the recently added "dar" variable, which
now correctly expresses the input Display Aspect Ratio value as
"(inw_w/in_h)*sar".
