Added bufferProducerGraphicBuffer struct. Parse the bufferProducerRequestBuffer parcel reply properly. Renamed bufferProducerTegraBufferInit to bufferProducerGraphicBufferInit + renamed the enum for it, and handle input/output for it properly. Properly return rc in bufferProducerGraphicBufferInit().
