If keepalive is disabled the existing code over-eagerly releases
DrmSession instances. This is arguably OK since a (Default)DrmSession
should be released before its (Default)Manager is released
(since the underlying MediaDrm instance might be released when the
manager is released). And if all sessions are released before the
manager is released then `sessions` is empty, so the loop is a no-op.

The `DrmConfiguration.sessionForClearTypes` property is often used
to ensure a secure decoder is used for clear ads played in encrypted
content. This is because some devices show black frames when switching
decoders.
Before this change the DRM config isn't propagated down when
constructing the ad media source, meaning
`DrmSessionManager.DRM_UNSUPPORTED` is always used, which will
cause playback to switch from secure to clear decoder when transitioning
to an ad break (ignoring the MediaItem `sessionForClearTypes` option.

It's used by the UI and mediasession modules. We may be able to move
it into the UI module if/when the mediasession module goes away.

Without this a new manager is instantiated for every item in a playlist,
meaning the impact of caching improvements to DefaultDrmSessionManager
are reduced (since the cache doesn't persist across playlist items).
With this change, playlists of items with identical DRM config will use
the same manager instance (and thus share existing sessions).

ControlDispatcher and DefaultControlDispatcher also need
to move to common for the UI module. As does PlaybackPreparer,
although that will be removed entirely in a future release.

- When throwing a recoverable error from a renderer, it's important to understand
exactly how the player will attempt recovery. Clarify the documentation to
make this explicit.
- Rename some methods/constants to make it clear that error recovery is specific
to renderer errors. The current recovery mechanism only makes sense for
renderer errors. Making the naming renderer specific avoids reader doubt that
the implementation doesn't appear to be generic enough for other types of
errors.

Before, the level was set to null in this case.
MediaCodecUtil.getCodecProfileAndLevel() was therefore returning null

Without this no error is currently logged or propagated to EventLogger.

This also moves DefaultHttpDataSource to common, which seems
sensible, else non-player components that need a DataSource
don't have any useful concrete implementations. We should
think about moving some of the other concrete implementations
to common as well.

- The order of sample stream (and thus the order in which loads are
triggered) currently depends on a Set and thus on the hash codes
of the objects that change with every run. Changing to a List solves
this problem.
- The FakeAdaptiveDataSet directly created a static Random (with random
seed) to compute the variation of chunk sizes. Changing this to an
injected Random object that can always be initialized with the same
seed also removed this randomness from the tests.

This is achieved by only triggering one message at a time. After
triggering a message we send another to ourselves to know when the
following message can be triggered.
Other required changes:
- The messages need to be sorted correctly (by time and creation order)
- To prevent deadlocks when one thread is waiting for another,
we need to add new method to Clock to indicate that the current
thread is about to wait. This then allows us to trigger messages
from other threads in FakeClock.
- AnalyticsCollectorTest needed some adjustments:
- onTimelineChanged now deterministically arrives after the initial
timline is already known, so some of the period information changes
from window only to full period info.
- The playlistOperations test suffers from a bug that the first frame
is rendered too early and that's why we now get additional events.

Currently only delayed messages are handled. Change this to handling
all messages so that we have more control over their execution order.
This requires adding a new wrapper type for the Message to support
the obtainMessage + sendToTarget use case.

They only require common. This allows their use for non-playback networking
without requiring the user to depend on the whole of core. I will also make
the same change for Cronet, although this needs a little more work.

`TrackSelection` had mutation methods which were to be called only
internally by ExoPlayer components but were exposed in the
public `Player` interface.
The mutation methods have been moved out of `TrackSelection`
to a new class `ExoTrackSelection`.
Current track related read-only method have also been moved out,
because they are actually something quite unclear.
Even for a single item playlist, it's the track being buffered rather
than the track being played, which is unclear.
But when you have a playlist it starts to get really confusing,
because if the next item is being buffered, then it's actually
the last track to be buffered in the currently playing item.
As a final aside, the implementations don't do proper thread synchronization
to ensure visibility of updated state by the calling thread.
Exposing those mutable methods in the public `Player` interface
was problematic because they leaking internal concepts of `ExoPlayer`.
This is also required to minimize the `Player` interface for long term
stability.
`ExoTrackSelection` is a subclass of `TrackSelection`.
This is not ideal as an `TrackSelection` implementation could
break the current immutability.
This was done in order for this refactor to be simpler.
A future patch will fully split the two classes.
All `MediaPeriod` and `Sources` had to be updated to use the new
`TrackSelection` dynamic aspect class name.
An alternative would have been to break ExoPlayer's public API, keeping
`TrackSelection` as the dynamic aspect name, and calling the public static
aspect class `TrackSelectionState` or similar.
Nevertheless, while it would have impacted less files, it would have
many more small apps and casual users of ExoPlayer.

`ImaAdsLoader` only loads ad media URLs once playback of the preceding ad (if
any) has started, and this behavior is likely to be similar for other ad loader
implementations due to limits on how long before an ad plays it is meant to be
loaded. This is problematic for very short ads followed by an ad because the ad
will load to the end but load control may not allow playback to start due to
the total buffered duration being low.
Fix this by allowing playback to start regardless of load control if we are
waiting for an ad media period to prepare.
An alternative fix would be to fake the ad progress in the `ImaAdsLoader` to
trigger loading the next ad, but this would only allow one ad to load ahead (so
the problem would remain for two short ads in a row followed by another ad).

This is necessary for the child cl that `TrackSelection`
in two distinct class. It avoids to split the array
version of such class too.
TrackSelectionArray exist to have an immutable array of TrackSelection.
Internal users are trusted to not mutate the array.
One drawback of this approach is that a `TrackSelectionArray`
has to be allocated on the boundary of the `Player` interface.
This should not be a performance issue as this only happens
on trackSelection changes, when the user calls
`Player.getCurrentTrackSelections` and on
`updateLoadControlTrackSelection`.

Codecs are not used by this test because PCM uses codec bypass,

verify that this is indeed the case!

- Once the ability to add debug listeners is removed, analyticsCollector
is the only component that needs to receive the events. Hence it is
called directly.
- It seemed less confusing to do the same thing for (non-debug) video and
audio events, and to have AnalyticsCollector no longer implement
VideoListener and AudioListener directly. This clears up confusion that
arises as a result of the debug and non-debug interfaces defining the
same methods in some cases, and having to be careful not to end up
calling the corresponding AnalyticsCollector method twice.
PiperOrigin-RevId: 351835491
AnalyticsCollector is allowed to be subclassed to simplify adding
new events that make use of the EventTime generation.
Clean up the subclassing interface to simplify this:
- Make generateCurrentPlayerMediaPeriodEventTime protected. This is
arguably the most useful method for extended clients. Other
generateXXXEventTime methods are left private as they can't be
useful for extensions because they require some integration into
the ExoPlayer playback thread to make sense. So keeping them
private to cause less confusion.
- Some existing callback handling should be final as all the others.
- Adding @CallSuper to all lifecycle management methods that might
be helpful to subclasses but require to call the super method.
- Make sendEvent protected to let subclasses use the simple
event sending method.
