Use internal PLC in Opus

Reported by tlegrand@google.com, Dec 3 2012

Issue description

Feature description (please include a link to the functional spec):

Opus has an internal PLC that help update the state of the coder in case of packet losses. The function is currently not used in WebRTC, but would enhance quality performance in case of lossy networks.

NetEq3 supported Opus PLC, but NetEq4 don't. Needs to be added to NetEq4.

Yes, it is.
does webrtc use opus PLC instead of expand/merge of neteq now?

No, it does not.

This bug is actually about calling the Opus PLC simply to let the decoder know that packets were lost, so that it can recover from the state fault faster.
