SoupHTTPRequest: O brave new world!

Kill SoupHTTPInputStream, and have SoupHTTPRequest return the
message's body_istream directly (with a little help from SoupSession
and its subclasses). SoupHTTPRequest works synchronously now as well
(though it's still the case that async only works with
SoupSessionAsync and sync only works with SoupSessionSync).

- * soup_http_input_stream_new:
- * @session: the #SoupSession to use
- * @msg: the #SoupMessage whose response will be streamed
- *
- * Prepares to send @msg over @session, and returns a #GInputStream
- * that can be used to read the response.
- *
- * @msg may not be sent until the first read call; if you need to look
- * at the status code or response headers before reading the body, you
- * can use soup_http_input_stream_send() or soup_http_input_stream_send_async()
- * to force the message to be sent and the response headers read.
- *
- * If @msg gets a non-2xx result, the first read (or send) will return
- * an error with type %SOUP_HTTP_INPUT_STREAM_HTTP_ERROR.
- *
- * Internally, #SoupHTTPInputStream is implemented using asynchronous I/O,
- * so if you are using the synchronous API (eg,
- * g_input_stream_read()), you should create a new #GMainContext and
- * set it as the %SOUP_SESSION_ASYNC_CONTEXT property on @session. (If
- * you don't, then synchronous #GInputStream calls will cause the main
- * loop to be run recursively.) The async #GInputStream API works fine
- * with %SOUP_SESSION_ASYNC_CONTEXT either set or unset.
- *
- * Returns: a new #GInputStream.
