buffer: clean up onload, fix console update

* reduce onload result size to a single int
* clean up mess that was the container onload handler

This fixes automatic refresh in console. Before, the client would
only request a screen update after receiving the number of bytes read,
but before the screen was actually reshaped (which obviously resulted
in a race condition). Now, "I've reshaped the document" is a separate
response (and is the only occasion where the screen is updated before
the final render).
