monitor: fix muxing

Browse source 
make the mux driver send mux_in and mux_out events when switching
focus while hooking up more handlers.

stop using CharDriverState->focus in monitor.c, track state using
the mux events instead.  This also removes the implicit assumtion
that a muxed monitor allways has mux channel 0.
