Martin Blapp 153c21c8c1 If /dev/tty gets opened after your controlling terminal has been revoked ...

you can't call tty_clone afterwords. OpenBSD and NetBSD both fail the
open call in that case, so we should do so as well. This can
be done in ctty_clone by returning with *dev==NULL. Admittedly this
causes open to return ENOENT, instead of ENXIO as on the other BSDs,
but this way requires the least touching of code.
