The DtlsSrtpTransport takes the reponsiblity of setting up DTLS-SRTP from the BaseChannel. The BaseChannel doesn't handle the signals from the P2P layer transport anymore. The RtpTransport handles the signals from the PacketTransportInternal and the DtlsSrtpTransport handles the DTLS-specific signals and determines when to extract the keys and setting the parameters. In channel_unittests.cc, call from DTLS to SDES is expected to fail since the fallback from DTLS to SDES is not supported.
