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.

4646ef87b1 lavfi: fix registration name for the buffersink sink 
Previously both the buffer and buffersink elements were associated to
the "BUFFER" symbol in allfilters.c, so it was not possible to enable
one without the other.
