cyclades: add tty refcounting
While this is not problem for Y card handlers (they are protected
by card_lock), Z handlers and other functions may dereference NULL
at any point after hangup/close. Even if (tty == NULL) was already
performed in the handler.
Note that it's not an issue for Y cards just for now. After
switching to tty_port_close_* et al. this will be a problem. So
add refcounting to them all.
Also proc .show doesn't take a tty reference and it should (along
with a ldisc one).
While at it and changing prototypes (adding tty param), prepend
cy_ to functions which don't have it yet.
