Added getRenderPosition() API to IAudioFlinger to retreive number of audio frames written by AudioFlinger to audio HAL and by DSP to DAC. Added getRenderPosition() API to AudioHardwareInterface to retreive number of audio frames written by DSP to DAC. Exposed AudioTrack::getPosition() to AudioSink() to make it available to media player. Removed excessive log in AudioHardwareGeneric.
