Finally commit the changes that make getty(8) no longer depend on the

COMPAT_43 cruft.  This is supposedly the last core utility that has
been using it!  (So now, one should be able to remove this option from
the config files.  Be aware that the last officially released xterm
however still requires it.)

The getty has been running now for several weeks on my modem line, so
i feel safe about it.
