Streams API: WritableStream

WritableStream is part of the Streams API for creating, composing, and consuming streams of data. It is the writable counterpart to ReadableStream, which is already shipping in Chrome. It provides a standard abstraction for writing streaming data to a sink, with built-in backpressure and queuing. This is expected to be on by default in Chrome 59.
