Patch for gst-plugins-bad that gives the opus codec the correct timings for PLC

These 3 patches combine to allow exact timings to be provided into the codec
when packets are lost.  Without this the codec has no idea of how long to
correct for and it turns out that this gives much improved packet loss
concealment.  In real life tests with WebRTC we found that opus audio went from
unintelligible to pretty good with the same level of packet loss.
