opensles: drop 48kHz sample rate
...
OpenSL ES implementation in Android is just a 'facade' API on top of
AudioFlinger which will downsample 48kHz into 44.1kHz before
delivering the audio to the underlaying hardware.
We found that it suffer some sort of underrun when the downsample
enters in action so relay on our good resampler to take care of that
and fix the clicks issue. And get an extra bonus of a lower latency.

opensles: change the defaults to use 20 ms ringbuffer segments
...
In my nexus7 seems that the internal min buffer size is 20 ms so make
our segments match.

opensles: cap queue size
...
Just in case we want to tweak the sink behaviour with buffer-time and
latency-time properties cap the queue size to something reasonable.

...
At start drain half ringbuffer into the OpenSL so the writting/reading
pointers will start at half ringbuffer distance.

opensles: rework on the ringbufffer to properly clear segments
...
Make the segments bigger (1 second) as it seems to be the minimum size
we need to not introduce noise.
Sink works in my nexus 7 with rates from 8000 to 44100 and some noise
can be noticed on higger sample rates.
