This function will be called whenever a concurrent update happened
to the iterated datastructure. The implementor of the iterator should
restart the iterator from the beginning and clean up any state it might
have.
Implementors of a gstreamer.Iterator should implement this
function and pass it to the constructor of the custom iterator.
The function will be called with the iterator lock held.
