Use single buffer queue callback for OpenSLES/Android

Working buffer size should be around 0.1-0.3 sec of data

- This appears to work on a wide grange of older Gingerbread through to the latest Nexus class devices
- TODO : we really should write a dynamic calculation/adjustment routine to determine the best working buffer for
any device this code runs on =)

Better OpenSLES backend implementation for Android

- Uses buffer values gleaned from Android system
- Removes completely unnecessary playq and uses ringBuffer instead with read/write heads
