[perl #122445] use magic on $DB::single etc to avoid overload issues
This prevents perl recursing infinitely when an overloaded object is assigned to $DB::single, $DB::trace or $DB::signal This is done by referencing their values as IVs instead of as SVs in dbstate, and by adding magic to those variables so that assignments to the scalars update the PL_DBcontrol array.
