This reduces the number of calls to the DataSpec constructor and minimizes the number of files that need to be updated when adding a new DataSpec parameter (ex: followup []

As the manifest and media data sources can be the same now, we can provide
a simplified constructor with just one data source factory.

This removes the need to populate the entire period for the common usage of
getting the uid from the period.

Also add default implementation to get period by uid.

The end position is needed to make the MediaPeriodId unique as multiple
content periods may only vary in this parameter.

This also simplfies some other comparisons where the end position needed to
be compared in addition to the media period id.

The number is shelved in calls to queue.clear() to keep it for the next
media period. However, the queue may also become empty by repeated calls to
advancePlayingPeriod which may happen when seeking to an unprepared period.

Currently, when the VideoRendererOutputCapturer updates output size, it will
set the new surface, then release the old surface. This can lead to problem
when both surface depends on EGL, since the second release() can release EGL
resources of the first surface.

This CL reverses this process, and ensures that the old surface is released before the new one is created.

Added constructor and field in source itself

Setting the transfer listener on the data source factories is only needed for debug
purposes, logging and for custom bandwidth metering which doesn't use the
player-provided bandwidth meter. As such, it is not compulsary and it should be easy
to set up the data source factory without a transfer listener.

This was only needed temporatily until we could ensure that the player always
provides a BandwidthMeter.

As part of this change:

- Don't apply the workaround on API level 27+. GTS coverage
  should prevent such devices from existing.
- Use Util.DEVICE consistently.
- Remove the "// Device name", which don't really add much
  but make extra work when updating the list.

This bandwidth meter is then forwarded to the track selection and as a transfer
listener to media and data sources.

When no bandwidth meter is specified in the ExoPlayerFactory methods, a static
singleton instance will be used.

When notifying the bandwidth listeners of new samples, the forwarded values
need to be final to prevent concurrent access. Putting the event forwarding
into a separate method ensures the values are final.

The sample queues haven't been created when the first init call
occurs. In this case we need to set sourceId when we subsequently
create the queues.

1. Copy label into derived formats
2. If audio is the primary track type, copy additional fields from
   the variant formats. This is probably a no-op in practice, since
   I don't think variant formats have these fields set anyway, but
   it seems like the right thing to do in case they ever are set in
   the future.

Note: It's a bit strange to use createXContainerFormat rather than
createXSampleFormat, but in practice the methods used here are
better matched for what we're trying to do.

After [] we support default font size for TTML, relative to the cellResolution of the document. However, this introduced a bug that makes TTML font-size in such case always follow the cellResolution font size, even when SubtitleView.setApplyEmbeddedStyles(false) and SubtitleView.setApplyEmbeddedFontSizes(false) were used.

This CL updates the fix so that the default font-size using cellResolution works in the same way as other embedded styles, and can be turned off using setters from SubtitleView.
