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.

- Avoid having two onPositionDiscontinuity events (seek and transition)
sent after a seek to another media item.
- Avoid triggering an onPositionDiscontinuity event after a timeline
change.

Includes fixes for the HTTP implementations, which previously
broke this contract specifically in the case when a server
responds to a range request with a HTTP 200 response. To fix
this case, skipping to the requested position is moved from
read() to open(). As a side effect, this nicely simplifies
CronetDataSource!

The API is a lot more useful if apps can rely on the fact
that the gain is linear and applied to all channels.
This is already guaranty by AudioTrack and should be too
by any reasonable implementation.

Given we're proposing to make reading from the end a non-error case,
it's important to check that we return the right thing from open(),
and that we read the right thing (i.e., nothing) once opened.
For now, this test allows quite a bit of permissiveness, in line
with other related tests. This will be tightened up in due course.

Latest LTS version is better than latest stable version because it will
be supported for longer.

Allow offload of gapless content even if gapless offload is not known to be supported by the device.
This is not exposed in the high level DefaultRendererFactory as most
users are expected to prefer fidelity to power savings.
