It is impossible to reuse iterator after `EINA_ITERATOR_FOREACH`(`eina_iterator_next`).
E.g.
```
eina_init();
eina_file_dir_list("/home/", EINA_FALSE, _print_cb, NULL);
it = eina_file_ls("/home/");
EINA_ITERATOR_FOREACH(it, f_name)
{
printf("%s\n", f_name);
eina_stringshare_del(f_name);
}
EINA_ITERATOR_FOREACH(it, f_name)
{
printf("Again %s\n", f_name);
eina_stringshare_del(f_name);
}
eina_iterator_free(it);
```
`Agian ...` is never printed.
Therefore, iterator always need `@move` tag to avoid unexpected behavior without
any error message.
