I think in general this is the right approach to do this, but I also ran into a few issues. E.g. one was that NSURLRequest takes an NSURL, hence it can’t be used as-is for a `CONNECT host:port …` request.

This may be the kind of thing that needs extension. (As an additional benefit, it would help on the client side, too—client-side URLRequests are equally unable to represent CONNECT method use.)

Personally, I imagine that libcurl would be handled by translating from `URLRequest` to its preferred structures, but there are different ways to handle that.

`bodyStream` is an `InputStream`, so is this an issue if you subclass `InputStream` to represent a socket (or, I suppose, the next Content-Length bytes of a socket)? Or is there some other issue here I'm not thinking of?
