Add support for asterisk characters when filling in the GELI password

during boot.

Change the last argument of gets() to indicate a visibility flag and add
definitions for the numerical constants. Except for the value 2, gets()
will behave exactly the same, so existing consumers shouldn't break. We
only use it in two places, though.
