In MatroskaExtractor TrueHD audio samples are joined into larger chunks. For
some streams the resulting chunked samples seem never to start with a syncframe.
This could result in playback of TrueHD streams getting stuck after seeking
because we could never read a syncframe at the start of a sample to determine
the sample size.

Instead of expecting to find a syncframe at the start of a sample, search for it
within the sample, to fix this issue.

Note: this means that we may search a few thousand bytes to find the sample
size, but the cost is only incurred for the first audio sample read.

This field (formerly "id") is almost impossible to use so far. Having setters
in the factories allows to specify custom tags for all media sources.

Also added a ExoPlayer.getCurrentTag() method to retrieve the tag of the
currently playing media source in a convenient way.

The data collector keeps track of active media periods to assign each event to
the correct media period and/or window. This information, together with other
information like playback position and buffered duration, is then forwarded
with the event to all registered listeners.

Previously the SonicAudioProcessor and SilenceSkippingAudioProcessor would track
their pending playback parameters and only apply them in flush(). Having the
values only take effect once flushed made the processors a bit more difficult to
use, especially because the value returned by isActive wouldn't update
immediately.

Make DefaultAudioSink only set the new speed/pitch/skip silence setting after
the audio processors have drained. This means it's no longer necessary to keep
track of pending parameter values and also fixes a bug where initial playback
parameters weren't applied because the audio processors weren't flushed while
uninitialized before DefaultAudioSink called isActive() on them.

The previous API allowed to pass in null to the constructors although variants
without listeners exist. That's why we need to handle these null values.

Previously it was necessary to create a new Sonic instance every time the
processor was flushed. Add a flush() method to Sonic so that it can be reused
when seeking. It still needs to be recreated when parameters change.

SonicAudioProcessor and SilenceSkippingAudioProcessor have methods for setting
parameters that are documented as taking effect after a call to flush(), but
actually the value returned by isActive() was updated immediately. Track the
pending values and apply them in flush() to fix this.

We currently refresh repeatedly in this case. According to the
DASH spec omitting minUpdatePeriod indicates that the manifest
does not change, and therefore we should not refresh. I think
it might be valid to omit minUpdatePeriod in a dynamic manifest
if relying exclusively on EMSGs to trigger manifest refresh.

This is in preparation for making it possible to flush a Sonic instance so that
it's not necessary to create new ones every time the processor is flushed.

There should be no behavior changes here.

Weirdly, the Android Javadoc indicates that it returns something
before the API level on which the same Javadoc states it was added.
In any case, we can simply not call the method to avoid the
warning, since we only use the value if the API level is at least
23 anyway.

Video renderers assume that the player position is advancing linearly while in
the started state. MediaCodecVideoRenderer schedules frames for rendering in the
future in the expectation that the player position is advancing.

This assumption is not currently true when using a position from the AudioTrack:
the player position can be fixed for (in the worst case) up to about 100 ms
before it starts increasing. This leads to an effect where the first frame is
rendered then a few other frames are rendered, then there's a pause before
frames start being rendered smoothly.

Work around this issue by checking whether the position has started advancing
before scheduling frames to be rendered in the future.

It might be preferable to make the audio renderer only become ready when its
timestamp can start advancing, but this is likely to be complicated.

In audio processors an audio frame consists of a sample (which is 2 bytes for
16-bit PCM) for each channel. Sonic used "sample" to refer to this.

We've already diverged from the original source for Sonic quite a bit (deleting
code and making stylistic changes) and there haven't been upstream changes so
far, so it seems fine to start making more substantial changes here.

There should be no behavior changes here.

This adds two options to the ClippingMediaSource which allow proper clipping
of live streams:
 1. The clipping stays fixed relative to already created media periods. That
    means that playback actually progresses through the clipped media and
    eventually reaches the end of the clipping. The window is also marked
    as non-dynamic to let playback end in this case.
 2. Allow to specify a clipping duration relative to the default position to
    be able to specify the duration of live stream which is to be played.
