Result: no hwbinder calls due music processing. Added IEffect.close method for explicitly freeing up of resources consumed by the effect before automatic server objects reaping gets to it. Added IEffect.setProcessBuffers method for updating the input / output buffers on the go. Test: make, use Play Music with effects, check traces Bug: 30222631 Change-Id: Ia1e1bc7098fab59aa970e0ce4acdb48007409644
