After an ad pod coming up has preloaded, if the user seeks before it
plays we get pauseAd/stopAd called for that ad pod. Also, the ad will
not load again. Work around this unexpected behavior by handling
pauseAd/stopAd and discarding the ad.

In future, it's likely that the IMA SDK will stop calling those
methods, and will loadAd again for the preloaded ad that was
unexpectedly discarded. This change should be compatible with that,
because the ad won't be discarded any more due to not calling stopAd.

Ads can appear due to asynchronous ad tag requests completing after
earlier ads in a pod have loaded, so remove the requirement that the
ad count can't change. The MediaPeriodQueue should handling discarding
buffered content if an ad appears before already buffered content, so
I think this case is actually handled correctly by the core player
already.

Also remove the requirement that an ad URI can't change. This is a
defensive measure for now, but it's likely that a later fix in the IMA
SDK for an issue where loadAd is not called after preloading then
seeking before a preloaded ad plays will result in loadAd being called
more than once, and I think it's possible that the second call to
loadAd may have a different URI. Because the ad URI should only change
after an intermediate seek to another MediaPeriod, there shouldn't be
any problems with buffered data not getting discarded.

The release() method was added in the recent IMA API changes for
preloading and now 'collides' with the ExoPlayer AdsLoader release
method. This led to all ads completing being treated as a call to
completely release the ads loader, which meant that the ad playback
state was not updated on resuming after all ads had completed, which
in turn led to playback getting stuck buffering on returning from the
background after all ads played.

Move the IMA callbacks into an inner class to avoid this.

- Leaving the TODO, since there are still MIME types we're unsure about.
- Removing AAC because xHE-AAC does not have this property. We may re-add
  it with an additional profile check to exclude xHE-AAC in the future.

We're then able to use this same helper class from tests, to avoid
running into spurious failures caused by long microseconds being
round-tripped through float seconds.

This is useful for debugging both in tests and via logging.

Some but not all VideoAdPlayer callbacks from the IMA SDK included
defensive handling of unexpected cases. Add the remaining ones.

In a later change it will be necessary to be able to destroy the ads
manager if all ads are skipped while creating ads rendering settings.
This change prepares for doing that by not having the ads manager
passed into the method (so the caller can null or initialize it).

This is in preparation for refactoring the logic to support not
playing an ad before the resume position (optionally).

Previously the fake ads loader listener would always pass the same ad
durations to the fake player, but actually the known ad durations can
change during playback.

Make the fake behavior more realistic by only exposing durations for
ads that have loaded.

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.
