* Entities transferred using this input stream can be of unlimited length.
* After the stream is read to the end, it provides access to the trailers,
* if any.

* Note that this class NEVER closes the underlying stream, even when close
* gets called. Instead, it will read until the "end" of its chunking on
* close, which allows for the seamless execution of subsequent HTTP 1.1
* requests, while not requiring the client to remember to read the entire
* contents of the response.
