Michael Lotz 16c5a72847 * Seperate out the tty_close_cookie from tty_destory_cookie and make the former
available as a module function as well.
* Remove some unneeded resetting from tty_destroy_cookie.
* Move the public module functions to the public API section of the file and
  order them by their declaration order in the module info.
