Change BufferQueue into producer/consumer wrapper

Now that BufferQueue has been split into core + producer + consumer,
rewrite BufferQueue to be a thin layer over a producer and consumer
interface. Eventually, this layer will be deprecated in favor of
only using either the producer or consumer interface, as applicable.
