Looks up the given item in the list store by looping over the items and
comparing them with equal_func until the first occurrence of item which
matches. If item was not found, then position will not be set, and this
method will return %FALSE.
item is always passed as second parameter to equal_func.
Since GLib 2.76 it is possible to pass NULL for item.
