pulsesrc: Implement GstStreamVolume interface
PulseAudio 1.0 supports per-source-output volumes, and this exposes the functionality via the GstStreamVolume interface. When compiled against pre-1.0 PulseAudio, the interface is not implemented, and the "volume" or "mute" properties are not available. This bit of ugliness will go away when we can depend on PulseAudio 1.0 or greater. https://bugzilla.gnome.org/show_bug.cgi?id=595055
