tty: rename tty_kopen() and add new function tty_kopen_shared()
Introduce a new function tty_kopen_shared() that yields a struct
tty_struct. The semantic difference to tty_kopen() is that the tty is
expected to be used already. So rename tty_kopen() to
tty_kopen_exclusive() for clearness, adapt the single user and put the
common code in a new static helper function.
tty_kopen_shared is to be used to implement an LED trigger for tty
devices in one of the next patches.
