If none of the extractors successfully sniff the content then we will fall back
to inferred file types in the following order:
- Webvtt if the media comes from a SUBTITLE EXT-X-MEDIA.
- The type of media declared in the HTTP "Content-Type" header.
- The type of the media according to the file extension.
- Transport stream.

Move offload events from Player.EventListener to
ExoPlayer.AudioOffloadListener.

Part of aligning HttpDataSource behavior will require adding
logic that's common across the DataSource implementations. This
change establishes a util class to house it, and moves a bit of
existing logic that's related and can be easily shared into it.

There is one small behavior change in this CL, which is that our
handling of Content-Range response headers can now parse the body
length if the "document size" part of the Content-Range is unknown,
for example "bytes 5-9/*". Previously the pattern we were matching
to required the "size" part to be set, for example "bytes 5-9/100",
despite the fact we don't need or use it.

These values must be null/empty while the source isn't opened. And the
Uri must be non-null if the source is open.

Adds a new Listener that extends all other listener.
This is part of the component flattening goal.

After components have been flattened in Player,
and clients transitioned, existing listeners will be deprecated.

Add additional assertions to try to figure out why
the tests are flaky when run in the test harness.

Failure could not be reproduced locally even after 4000 run.

ExoPlayer does not support seeking during ads.

TransferListener has the contract to have exactly one onTransferEnd per
onTransferStart, so the test can both assert that onTransferInitializing
is called, but not onTransferEnd (even after calling close).

It's more flexible to use FakeDataSource, since it allows to testing
different upstream behaviors (e.g., upstream not being able to resolve
the content length).

In a period transition we pass the start time of the next period, for
the final period we pass the duration of the period or timeline, if
known.

This means sideloaded subtitles now respect the end point of
ClippingMediaSource and ensures that content subtitles aren't
incorrectly displayed over mid-roll ads.

When transitioning back into the subtitled content the subtitles still
appear slightly before the video transitions, meaning the first subtitle
of the content is shown with the last few frames of the ad. Resolving
this in a way that doesn't break anything else requires a deeper
investigation.

MaskingMediaSource needs to resolve the prepare position set for a MaskingPeriod
while the source was still unprepared to the first actual prepare position.

It currently assumes that the period-window offset and the default position is
zero. This assumption is correct when a PlaceholderTimeline is used, but it
may not be true if the real timeline is already known (e.g. when re-preparing
a live stream after a playback error).

Fix this by using the known timeline at the time of the preparation.
Also:
 - Update a test that should have caught this to use lazy re-preparation.
 - Change the demo app code to use the recommended way to restart playback
   after a BehindLiveWindowException.

  sent after a seek to another media item.
- Avoid triggering an onPositionDiscontinuity event after a timeline
  change.
