Vicamo Yang 6997a6fa3c Bug 978709 - 2.b/6: don't use nsIRILDataCallback in GonkGPSGeolocationProvider. r=kanru
nsIRILDataCallback has been abused in RadioInterfaceLayer.js and is
becoming an RIL internal utility.  Besides, nsIRILDataCallback has
also racing problem as described in bug 976897.  We should really use
NetworkManager observer events to replace the notification mechanism
here.
