// Create an HTTP request with the supplied information.

// Unlike http.NewRequest:
//
//  *  This function doesn't mangle the supplied URL by round tripping it to a
//     string. For example, the Opaque field will continue to differentiate
//     between actual slashes in the path and escaped ones (cf.
//     http://goo.gl/rWX6ps).
//
//  *  This function doesn't magically re-interpret an io.Reader as an
//     io.ReadCloser when possible.
//
//  *  This function provides a convenient choke point to ensure we don't
//     forget to set a user agent header.
