Add GStreamer 1.0 audio support
Based on Christophe Fergeau's patch.
To enable audio with GStreamer 1.0: --with-audio=gstreamer1
There is only a few changes between those versions, worth mentioning:
- audio capabilities "audio/x-raw,format=..." instead of
"audio/x-raw-int,..."
- appsink signal for new data changed from "new-buffer" to "new-sample"
