This patch changes the names for emulated ttys from tty[C-J][0-9a-f] to
tty[C-J]{0..254}. 255 is reserved for the cfg device and thus cannot
currently be used.
This enables consistent addressing for all emulated ttys, and is
not unexpected to hit bits here and there; it is also a visible change,
as the getty(8) greeting displays the terminal name.
If more than 10 emulated ttys are in use (at least on the same display),
ttys(5) must be modified to reflect the new scheme.
