tty, ioctls -- Add new ioctl definitions for tty flags fetching

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 ]
