From: Cyrill Gorcunov <gorcu...@openvz.org>
This patch defines new ioctl codes TIOCGPKT, TIOCGPTLCK,
TIOCGEXCL for fetching pty's packet mode and locking state,
and exclusive mode of tty.
[ No real handlers for the codes though, this will be
addressed in another patch for easier review and
bisectability ]
