Previously, RTSP interleaved binary data is posted onto the playback thread
for handling, the playback thread then adds the received data to a queue.
A loader thread will later dequeue the data and process it.
In this CL, the binary data is sent through a separate listener, on
RtspMessageChannel's RTSP receiving thread.

NAT will block off incoming UDP connection because the router has no knowledge
of the necessary port mapping (the mapping is never set up because UDP is
connectionless).
The end result is, the UDP socket to receive RTP data will timeout. After the
`SocketTimeoutException` is caught, the following takes place to try streaming
with TCP (or, RTP over RTSP).
- `RtspClient` sends TEARDOWN to tear down the current session.
- `RtspClient` re-connect to the RTSP server.
- `RtspMediaPeriod` cancels all loading `RtpDataLoadables` (that are using UDP)
- `RtspMediaPeriod` constructs new `RtpDataLoadables` that use
`TransferRtpDataChannel`, and starts loading.
- Once the `RtpDataLoadables` are up and running, we are ready to receive.
`RtspClient` sends the SETUP requests.
- The rest of the flow is unchanged.

RTSP interleaving enables RTP packets to be sent using RTSP's TCP connection.
The interleaving RTSP messages contain binary data only and always start with a
'$'. Normal RTSP messages contain line breaks (CRLFs) that indicate complete
lines.

- Don't deprecate methods not deprecated in the base class and that
could one day be useful.
- Better document deprecation of other methods.

In RtpDataLoadable.load, the second UDP data source is opened on the port we
specify. If the port is already in use, a BindException is thrown.

Previously loadingFinished will never be set to true because it started in
false, and we are and'ing it with `canceled`.
