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.
