When we add DRM pre-acquire support to SampleQueue, we'll dispatch
twice the number of acquire and release events. This is slightly
confusing, since there's the same number of
DrmSessionManager#acquireSession() calls.

We can mitigate this by only dispatching each acquire and release
event to at most one EventDispatcher.

This also changes the events fired when playing a stream with both audio
and video encrypted with the same keys (even without pre-acquisition).

Before: The EventDispatcher would see 2 aquires, 1 key load and 2
release events.

After: The EventDispatcher will see 1 acquire, 1 key load and 1 release.

From media2 1.1.0, it supports API level 16 and above.

This is a no-op assuming the class is always used correctly.
When release causes referenceCount to reach zero there can be at most
one EventDispatcher still connected (which is the one that must be
passed to that final release() call), so we can always pass the event
directly to the EventDispatcher passed in to release().

Method override parameter nullness should contravariant.

There are two different patterns we use at the moment:
 1. Call both deprecated and non-deprecated method from call site with
    no default method implementation body.
 2. Use default method of non-deprecated method to call deprecated
    method.

Pattern 1 is easier to reason about as it makes the calls more explicit,
so changing all usages of pattern 2 to pattern 1.

This adds an optional DrmSessionManager#preacquireSession() method
and implements it on DefaultDrmSessionManager.

The manager doesn't promise to keep the preacquired sessions alive, and
will proactively release them if a ResourceBusyException suggests the
device is running out of available sessions in the underlying framework.

In a future change, SampleQueue will preacquire sessions on the loading
thread and keep track of preacquired 'references', releasing them
when seeking or clearing the queue.

Starting with Android 12 all components of an app that have an intent filter need to have an explicit attribute android:export that is set to either true or false. If a component filters for the MAIN or a VIEW action it needs the attribute explicitly set to true. Prior to Android 12 these were exported implicitly.

We already report these errors through callbacks to interested listeners.
However, to ease debugging with bugreports and local error detection,
it's helpful to also log these non-fatal execptions to logcat. Otherwise
nothing in logcat indicates that the player recovered from an exception.

This is preferable to just logging to LogCat so that listeners can
report this to analytics systems if required.

The SampleStream.readData contract is that when reading a sample
with a flags-only buffer, the buffer timestamp and flags should
be set and the read position should not be advanced.

`ImaAdsLoader` will preload the first ad of a subsequent media item, but the
preloaded ad might not actually play because the user could seek to a non-zero
position in that media item (which could trigger playback of a midroll, not the
preroll). In this case, playback would get stuck because the midroll ad
expected to play after the seek would never load, because the IMA SDK expected
the preroll to play first.

Fix this behavior by discarding the preloaded ad break. If there isn't a seek,
the transition to the next media item is still seamless.

This type is different to the selection reason, which is
dynamic (i.e., corresponds to the individual selected track,
which can change during playback). The static type is
exposed via TrackSelection, where-as the selection reason
will be internal to the core (i.e., player) module.

Previously it was safe to query the first period in the timeline, but
now we support using the ads loader in concatenations we need to use
the current period index instead.

These have limited value, and are confusing because they're only
actually used if the override only selects a single track (if the
override is an adaptive selection then the values are never used).
The simpliest path forward is to remove them.

than IAE. Now, Bundleable implementation may utilize checkNotNull for

The source can be used in compositions (in fact, every source is
automatically used in an internal composition when constructing the
playlist), and there is not really a concept of top-level media source
any more since the Player supports playlists.

The actual restriction is that the content media source needs to have
exactly one period to be able to create a SinglePeriodAdTimeline.
