Re: [streams] Readable byte streams should support an internal queue (#353)

Please suppose that the BYOB interface of a stream is given a Uint16Array with 1 element (i.e. backed with 2 byte long ArrayBuffer), and the stream is EOF-ed with only 1 byte of data. We planned to return an instance of the same ArrayBufferView variant, so, we want to return a Uint16Array. The stream has only 1 byte to return to the user, but we cannot create a Uint16Array and make it indicate that only 1 byte valid data has been saved into it.
