This is a breaking change for many consumers of the 'Response' and all
consumers of the 'Body' API. The summary of breaking changes is:
* 'Response::body()', 'Response::body_mut()' are infallible.
* A 'Body' can represent an empty body in more cases.
* 'ResponseBuilder' is now simply 'Builder'.
* Direct body read methods on 'Response' were removed in favor of
chaining through 'body_mut()': 'r.body_mut().to_string()'.
* Notion of a 'chunked_body' was removed as it was inaccurate.
* Maximum chunk size can be set on any body.
* 'Response' no longer implements 'Responder'.
A few bugs were fixed in the process. Specifically, 'Body' will emit an
accurate size even for bodies that are partially read, and the size of
seek-determined bodies is emitted on HEAD request where it wasn't
before. Specifics on transport were clarified, and 'Body' docs greatly
improved as a result.
