TIOCTTYGSTRUCT

Hi Ted,

Would you mind if I removed TIOCTTYGSTRUCT?

I suppose you don't need it any longer, and otherwise
could easily add some debugging stuff again when needed.
This ioctl exports lots of kernel-internal stuff that
userspace has no business looking at.
The direct reason I ask is that it also exports a kdev_t,
and the meaning of that will change.

        * tty_io.c (tty_ioctl): Add support for the new ioctl
                TIOCTTYGSTRUCT, which allow a kernel debugging program
                direct read access to the tty and tty_driver structures.
