When working with SSAI ads, we need to easily convert positions between
the underlying stream and the media model that exposes ad groups. To
simplify this, we can add util methods (that are testable on their own).
In addition, we need an easy way to build AdPlaybackStates for SSAI
inserted ads. The metadata is obtained out-of-band and usually has the
ad group start and end times in the underlying stream only. Hence, we
also add a util method to add a new ad group based on this information.

There are two main changes that need to be made:
1. Whenever we determine the next ad to play, we need to select a
server-side inserted ad even if it has been played already (because
it's part of the stream).
2. When the Timeline is updated in the player, we need to avoid changes
that would unnecessarily reset the renderers. Whenever a Timeline
change replaces content with a server-side inserted ad at the same
position we can just keep the existing MediaPeriod and also if the
duration of the current MediaPeriod is reduced but it is followed by
a MediaPeriod in the same SSAI stream, we can don't need to reset
the renderers as we keep playing the same stream.

Content after ad groups currently always resumes at the ad break position (unless
overridden by a seek or similar). In some cases, media inserting ads wants to
specify an offset after the ad group at which playback should resume. A common
example is a live stream that inserts an ad and then wants to continue streaming
at the current live edge.
Support this use case by allowing ad groups to specify a content resume offset
and making sure that the content start position after the ad group uses this offset.

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.

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.

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.

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)

All `add*Listener` and `add*Output` methods are
deprecated in favor of `addListener`.
As for the class themselves `VideoListener` and
`AudioListener` are not used internaly by ExoPlayer,
`VideoRendererEventListener`
and `AudioRendererEventListener` are use in their
place.
As a result `VideoListener` and `AudioListener`
can be deprecated in favor `Listener`.
On the other hand `TextOutput` and `MedataOutput`
are used both in the player interface and internally in
renderers.
This means that those class can't be deprecated.
There usage in the public interface are indirectly
deprecated as their is no way to use them without
using the deprecated `add*Output`.
Thus it's not an issue that the class themselves are
not deprecated.

Move VideoSize in the common module and have the Player return it.
`Listener` and `AnalyticsListener` `onVideoSizeChanged` are updated
with the old method deprecated.
`VideoRendererEventListener.onVideoSizeChanged` was also migrated to
`VideoSize` but the old method is removed, not deprecated.
This is because:
- apps calling/listening to this method is a rare and niche use-case.
- it would introduce hard to diagnostic issues where if only the caller
or the callee is updated to use the new method, the event will be lost.
This doesn't occur with the other 2 listeners as the caller is always
in ExoPlayer library and was updated to call both the old and new methods.
VideoSize is used everywhere except in `Format` as this would lead to
too much refactoring and backward compatibility breakage for little gain.

1. Clarify intention of getAdGroupIndexForPositionUs and
getAdGroupIndexAfterPositionUs. Both methods are used for very
specific but different purposes and encode the logic of which
ads should be played at which time, so it's helpful to clarify
this in the documentation as well.
2. Change one usage getAdGroupIndexForPositionUs to use the already
existing nextAdGroupIndex. This is also more in line with the
intended usage as clarified in step 1.
3. Update MediaPeriodQueueTest for updateQueuedPeriods to only
look for duration changes in future periods, not in the
current one, because that's not handled MediaPeriodQueue for ads
and the test is just passing by chance now. Also remove wrong
advancePlaying() calls that are already implicitly included in
the preceding enqueueNext() call.
4. Fix a minor bug where post-roll ads are not checked whether they
are played already before using them as the next ad group. Also
added a test covering this case.

Release is a life cycle operation that should only be called when
the player is no longer needed. It's linked to the player lifecycle
and thus very different from prepare/stop.
As a result, it should not be in the same command.
Additionally it's not clear if remote players will ever need to call release,
as the player creator is best candidate to release it.
As a result the release operation doesn't have a use case for a command.
A release command can be added later if a need is identified.

MediaCodecRenderer is calling its protected methods
resetCodecStateForRelease() and resetCodecStateForFlush() from its
constructor. Classess that override the methods (eg.
DebugMediaCodecVideoRenderer) need to checks if the methods
are called from the superclass constructor thus their members are not
initialized yet.
With this change, the MCR constructor does not call the two
methods and sets the respective state directly on its fields.

Remove references to deprecated methods. I didn't replace the DRM info
with references to non-deprecated methods because I'm not sure it
