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.

The player already supports changing durations of periods and ads.
The only thing not yet supported is a change in ad break positions
which changes the duration of clipped content ending in an ad break.
Adding support for this requires updating the end position in
MediaPeriodInfo and changing the clip end position of the respective
ClippingMediaPeriod.

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.

The method to handle Timeline updates currently uses
isAd() || isPlaceholder()
to trigger two things:
1. Using the existing requested content position as the content
position.
2. Re-resolving the content position from window to period in case
it changed since the last update.
The condition is correct for case (1) because ads must use the content
position (and not the position in the ad) and a placeholder period must
keep using the requested content position as well until the media
information is no longer a placeholder.
However, case (2) only needs to be done if the content position is
C.TIME_UNSET (to start at the default position) OR if the period is
still a placeholder and we want to re-resolve the position.
The case where re-resolution shouldn't be done is for ads with a non-
placeholder period and a concrete content position. This likely only
affects ads in live stream where the content position is currently
moving with the live stream instead of staying where it is.

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

The existing code results in flaky tests, where sometimes the write
fails (with "EPIPE (broken pipe)") and the exception propagates out
and causes the test to never complete and time out.
Swallowing the exception resolves this flakiness.

First intention to support parsing MPEG-H 3D Audio in ExoPlayer is to
take advantage of parsing capability from MediaParser API in AOSP.
Just with this change ExoPlayer does't support decoding MPEG-H 3D Audio
but can support decoding either by adding decoder with an extension or
by using Android OS which has decoder capability with MediaCodec API.
It was originally introduced because it was guaranteed to be non-null
unlike the inherited field. But ExoPlaybackException.cause has been
nullable for some time, so there's no gain in not using the inherited
field.

Also make future similar issues less likely by adding isPlaceholder
to the set method of Period (in case forwarding Timeline
implementations use this instead of just updating values selectively)
