monitor: Improve mux'ed console experience (Jan Kiszka)

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.
