Currently the audio renderer can become ready before the AudioTrack
actually has enough data to play something, which means that the
player may transition to the ready state before audio starts
playing. This makes the player's current state transition not very
useful for detecting when audio actually starts playing.
This change adds a new event to notify apps when the audio position
is increasing after a pause or seek/flush/reset event, and includes
an estimate of the system time at which audio playout started.

AudioTrack.setPlaybackParams can be used to adjust playback speed.
This is preferable to application-level speed adjustment (currently
implemented in ExoPlayer) from API 23 because the speed change
occurs in the mixer, which means that the audio track buffer doesn't
need to drain out before the speed adjustment takes effect.

Find sbgp and sgpd boxes with grouping_type == seig in the case they don't
come first. Previoulsy we would only find them if they came first.

The working of libOpus is different from ffmpeg. With ffmpeg, the decoder can
be configured to output floating point PCM. While in libOpus, floating samples
are acquired by calling a different function. This is the reason the new JNI
functions and the logic in OpusDecoder/LibopusAudioRenderer is added to
support float output.

This callback was not notified before, which could theoretically lead to ad
loading timing out. In practice it doesn't currently happen because the timeout
appears to start when the ad cue point is reached, not when loadAd is called.
We notify onLoaded when the ad media period is prepared (for HTML5 the
recommendation is to notify on the HTMLMediaElement 'canplay' event, which this
roughly corresponds to).

Issue: #7244 added this feature to HLS. This change is the exact copy
in ChunkSampleStream to add the same support to the other adaptive
formats.
Note that ChunkSampleStream doesn't support slicing, so we can't cancel
a read-from chunk, and we need to prevent reading into an already
canceled chunk load so that the chunk can be automatically discarded
after the cancelation.

*** Original commit ***
Pass startPositionUs into Renderer.replaceStream
Plumb this down into BaseRenderer.onStreamChanged and use it when
deciding whether to render the first frame of a new period.

These callbacks were only necessary to track the queue in AnalyticsCollector and there is no other known benefit of having them.
