aio: update to latest, windows, code reuse
Update to latest aio, which has minor changes such as the thread pool argument and special aio.ReadTty operation. In future the aio.ReadTty might have option to translate to vt escape sequences, but for vaxis it will use the direct mode. I was not really able to test the windows at all actually as wine did not seem to play nice with any vaxis example, but it compiles and ... runs?
