1f4652068e lavfi: rewrite nullsrc using the code in vsrc_testsrc.c
Factorize code, extend the functionality of the filter, and make it
return empty buffers. This is useful for filters which ignore the input
frames content.

This is also changing the syntax of the nullsrc source, and dropping the
framerate expression evaluation, which does not look particularly useful.

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

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

Zaki, performed for the GSoC 2010 and 2011.

c4415f6ec9 lavfi: unify asink_buffer and vsink_buffer API

(only for the video binary interface, audio interface was never used
in the tools).
