3D audio

At this moment Android OS does not provide any out of box solution for rendering spatial audio. For example like XAudio 2.9 on Windows. So it's need to implement similar system. The mandatory feature set is the following:

• [x] listener with position and orientation
• [x] sound source with position
• [x] global sound source
• [x] stereo speaker configuration
• [x] wav uncompressed format support
• [x] ogg format support
• [x] audio streaming for long files
• [x] stereo/mono sound assets @44100 Hz ,16bit signed PCM
• [x] lua scriptable entity
• [x] hardware volume +/- buttons support
• [x] auto-pause/resume at activity lost/gain focus event
• [x] correct audio endpoint change handling (wired headset disconnection, lost Bluetooth connection)

All goals have been achieved. Closing task.
