Subject: 3824 - experiment: stop buffering in termbox

Now it's much more apparent why things are slow. You can see each repaint
happening. Already I fixed one performance bug -- in clear-rest-of-screen.

Since this subverts Mu's fake screen there may be bugs.

Another salubrious side effect: I've finally internalized that switching
to raw mode doesn't have to clear the screen. That was just an artifact
of how termbox abstracted operations. Now I can conceive of using termbox
to build a repl as well.

(I was inspired to poke into termbox internals by
http://viewsourcecode.org/snaptoken/kilo and
