When using the CronetEngine.Builder class, it automatically selects the
Cronet version preferring higher version codes and falling back to a Java
Http implementation if no native or GMSCore version is available.
This version selection has now been moved into the CronetEngineFactory
class to always prefer GMSCore over natively bundled versions. We also
ignore the Cronet internal Java implementation. Instead, users of
CronetDataSourceFactory can provide their own fallback factory. If none is
provided, we use DefaultHttpDataSourceFactory.
