commit 8064c6c827c1aabfb23231eca4221c400a60fc65
Author: Bastien Nocera <hadess hadess net>

Add private gnome-volume-control library
The library is introspected, and should not require using
Pulseaudio directly.
With help from Giovanni Campagna <scampa giovanni gmail com>
(introspection annotations, build fixes)
