AudioAttributesCompat.

Some APIs accept only AudioAttributes and do not allow
legacy stream types. This class is the first step toward
remedying that; it is a compat lib implementation of the
AudioAttributes structure and type<->stream conversion.

On API21 and later it is a simple wrapper around platform
AudioAttributes. Prior to API21 it holds a stream type.

Future compat versions of other APIs should accept
AudioAttributesCompat where the framework version accepts
AudioAttributes.
