[PATCH] Fix tty layer DoS and comment relevant code

Unlike the other tty comment patch this one has code changes. Specifically
it limits the queue size for a tty to 64K characters (128Kbytes) worst case
even if the tty is ignoring tty->throttle. This is because certain drivers
don't honour the throttle value correctly, although it is a useful
safeguard anyway.
