[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.
