boot/console: handle consoles that fail to probe
- clarify meaning of console flags
- perform i/o via a console only if both of the following conditions are met:
o console is active (selected by user or config)
o console flags that it can perform the operation
- warn if a chosen console can not work (the warning may go nowhere without
working and active console, though)
