Turn sgtty into a binary-only compatibility interface.

sgtty was the original interface to configure terminal attributes on my
UNIX-like operating systems. It has been deprecated by the POSIX termios
interface, which is implemented in almost any modern system.

An advantage of turning this into a binary compatibility interface, is
that we can now eventually remove the COMPAT_43TTY switch from kernel
configurations. This removes many ioctl()'s from the TTY layer.

While there, increase the __FreeBSD_version, which may be useful for the
people working on the Ports tree.
