preliminary support for avconv/avprobe from libav

avconv is capable of outputting to the .sox format, greatly
simplifying our life as it enables us to easily apply sox
effects on a per-source file basis.

dtas-sourceedit and the "source" protocol commands will need
to change to support internal priorities (like sink).
