This change integrates the FrameDecryptorInterface and the FrameEncryptorInterface into the audio media path. If a FrameEncryptorInterface is set on an outgoing audio RTPSender then each outgoing audio payload will first pass through the provided FrameEncryptor which will have a chance to modify the payload contents for the purposes of encryption. If a FrameDecryptorInterface is set on an incoming audio RtpReceiver then each incoming audio payload will first pass through the provided FrameDecryptor which have a chance to modify the payload contents for the purpose of decryption. While AEAD is supported by the FrameDecryptor/FrameEncryptor interfaces this CL does not use it and so it is left as null.
