structs: Fix printing of IDs

These types are used as values (not pointers) in other structs. Using a pointer receiver causes
problems when the value is printed. fmt will not call the String method if it is passed a value
and the String method has a pointer receiver. By using a value receiver the correct string is printed.

Also remove some unused methods.
