OpenSL ES stability improvements

OpenSL ES stability improvements.

This CL does two things:

1) Improves stability in the existing OpenSL ES implementation for devices that
supports OpenSL ES. The cost is a slight increase in latency since the focus here
has been on avoiding audio glitches.

2) Adds a new Java API to exclude usage of OpenSL ES to enable comparisons between
OpenSL ES and Java based audio backends.

Application can now do

import package org.webrtc.voiceengine.WebRtcAudioManager

and then calll

WebRtcAudioManager.setBlacklistDeviceForOpenSLESUsage()

to enable/disable OpenSL ES. This call also overrides any
existing blacklisting.
