EchoControl factory injectable in AudioProcessing.
This CL enables a factory method creating acoustic echo cancellers
that inherit EchoControl to be injected into the audio processing
module. AudioProcessing will call the factory method to create an
instance of the EchoControl subclass when needed. In the event of
sample rate changes, AudioProcessing will recreate the object using
the factory method.
