drivers/console: Handle basic control characters cleanly
By default, since we don't have special support for control characters
we should simply ignore them. This includes both pure (single) control
characters as well as ANSI escape sequences. The most important
control character to support for basic editing is Backspace.
The terminal creates a Delete (DEL) character by default when
Backspace is pressed. It also treats the Backspace character ('\b') as
a non-destructive backspace. To create the effect of destructive
backspace we have to send the sequence "\b \b".
