SDK / exoplayer

The parameters staying in DefaultTrackSelector are considered
too ExoPlayer specific to be part of the `Player` interface.
Those are:
 - exceedVideoConstraintsIfNecessary;
 - allowVideoMixedMimeTypeAdaptiveness;
 - allowVideoNonSeamlessAdaptiveness;
 - exceedAudioConstraintsIfNecessary;
 - allowAudioMixedMimeTypeAdaptiveness;
 - allowAudioMixedSampleRateAdaptiveness;
 - allowAudioMixedChannelCountAdaptiveness;
 - disabledTextTrackSelectionFlags;
 - exceedRendererCapabilitiesIfNecessary;
 - tunnelingEnabled;
 - allowMultipleAdaptiveSelections;
 - rendererDisabledFlags

Track selection override will be migrated in a follow up cl.

To avoid breaking backward compatibility,
`DefaultTrackSelector.Parameters` extends
`TrackSelectionParameters` and
`DefaultTrackSelector.ParametersBuilder` extends `TrackSelectionParameters.Builder`.
The change are thus transparent for clients.

Test are incomplete for now, as this is a relatively big cl, I though
the reviewer could give a first pass will the tests are completed.
