SDK / exoplayer

When the player state is changed from an event listener callback, we may
get recursive listener notifications. These recursions can produce a wrong
order, skip or duplicate updates, and send different notifications to
different listeners.

This change serializes listener notifications by clustering all update data
in a helper data class and adding the updates to a queue which can be handled
in a loop on the outer layer of the recursion.

As playWhenReady updates also reference the current playbackInfo, we need to
redirect the listener notifcations for setPlayWhenReady to the same queue.

Saving current subtitle cues on SimpleExoPlayer

[extension-ffmpeg] repeatable build instructions

Currently, the sample queues are lazily enabled when they are first read from.
This causes problems when the player tries to discard buffer and the
HlsSampleStreamWrapper assumes the sample queue is disabled even though it's
actually enabled but hasn't been read from.

This change moves setting the sample queue index of the sample stream back into
HlsSampleStreamWrapper. It enables the sample queues at track selection if the
queues are already built, or immediately after they have been built for
chunkless preparation.

InstrumentationTestCase has been deprecated, and it does not offer some useful
features, such as targeting SDK version level for tests, or skipping tests if
necessary.

A new playback nonce is created for each playback of the same item. Thus we
need to inject the nonce dynamically into the data source factory.

This CL adds the DataSource which does the actual insertion into the request
URLs and a MediaSource which listens to new media periods, to request the
nonce and to configure the data source factory for this media period to use
this nonce.

For TTML, if the font size is expressed in %, the font size should be relative
to the cellResolution of the document which we did not support before. This CL
adds support for handling this correctly.
Note that this still does not support font size using c unit.

Currently, ExoPlayer only supports seeking for FLAC files with a SEEKTABLE.
This CL adds support seeking for cases when the FLAC files do not have a
SEEKTABLE by searching for individual frames within the file using binary
search.

Due to a bug, for each TTML node, when applying its style to the encompassed
regions, it applies child nodes's styling several time for each region (the
number of time is equal to the number of region). This leads to a styling issue
if there are multiple regions in a node displayed at the same time in TTML file.

The lint error suppression only works locally and not for external developers
who still see the lint error and need to suppress it themselves.

This changes 'implementation' to 'compileOnly' in gradle to prevent the
dependency from being exported. Also removes the local lint suppression.
