Merge fix for #7193 into dev-v2-r2.11.5

We currently have a currentMediaPeriodId and an activeSessionId that are more
or less tracking the same thing unless the current media period isn't "active" yet.

Simplify this logic by using a single currentSessionId field and the respective
isActive flag of this session. Also move all session creation and activation code in
the same method to make it easier to reason about the code.

This change also fixes a subtle bug where events after a seek to a new window
are not ignored as they should.

Currently, this method is only supposed to be called before removing
the listener from the player or when releasing the player.

If called at other times, it will throw an exception later when
a playback session is ended automatically.

The first session should only be created once we have the media items
and/or called prepare. Otherwise the first session is created with
an EventTime having an empty timeline making it less useful.

The ad break time in seconds from IMA was "-1" for postrolls, but this didn't
match C.TIME_END_OF_SOURCE in the ad group times array.

Handle an ad break time of -1 directly by mapping it onto the last ad group,
instead of trying to look it up in the array.

Detect stuck buffering cases in ImaAdsLoader, and discard the ad group after
a timeout. This is intended to make the IMA extension more robust in the case
where an ad group unexpectedly doesn't load.

The timing out behavior is enabled by default but apps can choose to retain
the old behavior by setting an unset timeout on ImaAdsLoader.Builder.

Put static methods at the end.

Also add a couple of missing parameter name comments.

Log content progress events, as these are helpful to debug triggering of events
based on the content progress.

Don't log AD_PROGRESS events as they occur several times per second while ads
are playing, and the verbosity makes logs difficult to read.

adPlaybackState is now non-null, and the uninitialized case is covered by a new
boolean hasAdPlaybackState. Position progress updates are now non-null and
initialized with IMA's VIDEO_TIME_NOT_READY constant.

Also fix some misc code issues:
- Remove empty branch for SmoothStreaming (Android Studio warns about this).
- Tidy onTimelineChanged and onPositionDiscontinuity and the methods they call
  to improve naming.
- Remove logging for IMA events after release, as these methods are expected to
  be called in the current IMA SDK behavior.

The mocking setup is quite messy/unclear compared to the fakes, but it seems
worth switching over because IMA API changes have already required changes
to fakes in the past, and there are more API changes in the version we are
about to upgrade to. This change should generally remove the need to keep
the fakes up-to-date.

The positions were interchangeably used with window and period
positions. This change more clearly ensures that all positions in the
AdPlaybackState are based on periods and that we use the right adjustments
for all usages.

This tests explicitly that initialization happens even if the Timeline
is a placeholder.

No other change is needed. While the Timeline is still a placeholder
ImaAdsLoader.getCurrentPeriodPosition will return 0 and trigger
pre-rolls (intended behaviour) and it doesn't matter whether the
actual initial period position may be somewhere else.

This change is similar to e8293b92
but without relying on new player events that haven't been released
yet, to make it easier to merge changes related to ImaAdsLoader on
top.

ImaAdsLoader relies on preloading being enabled (it doesn't
work without it) so we may as well remove the constant to
avoid potential confusion.

 - Add method to scale scrubber handle of DefaultTimeBar

The capture frame rate is currently available both via Format.metadata
and decoded in Format.frameRate. As the container Format.frameRate may
be useful to apps, only store the capture frame rate in metadata (apps
will need to decode it but can now access the container frame rate too).

We keep an index hint for the next pending player message. This hint
wasn't updated correctly when messages are removed due to a timeline
update.

This change makes sure to only use the hint locally in one method so
that it doesn't need to be updated anywhere else and also adds the "hint"
suffix to the variable name to make it clearer that it's just a hint and
there are no guarantees this index actually exists anymore.

The MediaSessionConnector gets a Bundle passed to the MediaSession.Callback
from the framework which can be null. This needs to be properly annotated
with @Nullable.
