stagefright: Resurrect PCM offload
* Forward-port the open-source code from L which was moved to closed-source
in M. This is being done out of necessity- the architecture chosen by
Qualcomm is not optimal and doesn't work well with a singular
codebase which attempts to service a large number of devices.
* This patch brings in the code to support PCM offload (AudioFlinger
bypass). This allows for playback of high resolution clips without
decimation stages, and enables reduced power consumption for audio
pipelines which take advantage of the Hexagon DSP (effects).
