aaudio: prevent onAudioDeviceUpdate past close
To prevent late device update callbacks, the AudioStream
was made into a RefBase AudioDeviceCallback.
So now we can use a smart pointer to delay deletion of the
stream if any callbacks are in flight while the stream is closed.
So an AudioStream is now a RefBased object and can be used with
android::sp. That required some changes to the way it is referenced
in several places.
MyPlayerBase was modified to use a weak pointer to the parent stream.
Use delete[] for mDistributionBuffer
