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 will allow deduplicating the argument from all Loader clients.

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.

For the MetadataRetriever, for certain queries, after setting up the player to
render a frame (by seeking to the position), sometimes the player will seek to
the same position and ignore the seek, leading to the frame not being captured,
leaving the retriever in deadlock, waiting for the frame forever. This CL adds
a retry timer to avoid this and make sure we can return query result after some
time.

1. Prefer label and language values in the manifest to those in
   the media. This is particularly helpful if the sample format
   contains "und" as the language.
2. Copy label when deriving formats in HlsSampleStreamWrapper
3. When there's only one variant in HlsSampleStreamWrapper, use
   the regular copyWithManifestFormatInfo. This allows more
   information to be retained from the sample format.

That allows to add listeners after the BandwidthMeter has been created which is
helpful as the BandwidthMeter instances are often long-lived static instances.

Add supports for reading duration for a PS stream by reading SCR values from
the header of packs at the start and at the end of the stream, calculating the
difference, and converting that into stream duration.
