Up to now, you never really knew if you already switched the console after pressing CTRL-A C or if you mistyped it again. This patch clarifies the situation by providing a prompt in a new line and injecting a linebreak when switching away again. For this purpose, the two events CHR_EVENT_MUX_IN and CHR_EVENT_MUX_OUT are introduced and distributed on focus switches.
