Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
...
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point
...
in each tty driver to indirect through it.
This allows tty line-disciplines to handle poll(2) system calls.

Remove unnecessary test of tp->t_linesw against NULL; they are results
...
of confusion while correcting compilation error after t_line is
replaced with t_linesw.
