This adds a new pair of interfaces called producer and consumer which are simpler (in that they don't hold onto the underlying queue) than the stream interfaces. This makes it easier to share a single queue between the endpoints that will manipulate it. It was not possible to share a queue between two objects that implemented the in_stream and out_stream interfaces. This also adds a pair of adaptors that can convert a producer or consumer into a stream of the correct type. These adaptors will be used for existing code once the usb-stream and usart drivers are converted over to use the producer/consumer interfaces instead of the stream interfaces.
