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.

-.Os
-.Sh NAME
-.Nm stty ,
-.Nm gtty
-.Nd set and get terminal state (defunct)
-.Sh LIBRARY
-.Lb libcompat
-.Sh SYNOPSIS
-.In sgtty.h
-.Ft int
-.Fn stty "int fd" "struct sgttyb *buf"
-.Ft int
-.Fn gtty "int fd" "struct sgttyb *buf"
-.Sh DESCRIPTION
-.Bf -symbolic
-These interfaces are obsoleted by
-.Xr ioctl 2 .
-.Ef
-.Pp
-The
-.Fn stty
-function
-sets the state of the terminal associated with
-.Fa fd .
-The
-.Fn gtty
-function
-retrieves the state of the terminal associated
-with
-.Fa fd .
-To set the state of a terminal the call must have
-write permission.
-.Pp
-The
-.Fn stty
-call is actually
-.Ql ioctl(fd, TIOCSETP, buf) ,
-while
-the
-.Fn gtty
-call is
-.Ql ioctl(fd, TIOCGETP, buf) .
-See
-.Xr ioctl 2
-and
-.Xr tty 4
-for an explanation.
-.Sh DIAGNOSTICS
-If the call is successful 0 is returned, otherwise \-1 is
-returned and the global variable
-.Va errno
-contains the reason for the failure.
-.Sh SEE ALSO
-.Xr ioctl 2 ,
-.Xr tty 4
-.Sh HISTORY
-The
-.Fn stty
-and
-.Fn gtty
-functions appeared in
