Get the number of columns with gtk_tree_model_get_n_columns()
and their types with gtk_tree_model_get_column_type(),
create a new list store with gtk_list_store_newv().
Iterate over rows, in each row iterate over columns, fetch
values with the generic method gtk_tree_model_get_value()
ans store them with gtk_list_store_set_value().

Of course, the copy will be be still shallow.  If you want
a deep copy, you have to know how to deep-copy values like
objects or raw pointers (which is generally impossible) if
they can be present.
