Just 

       virtual void _M_reserved1() {}
       virtual void _M_reserved2() {}

suffices.  When we use them, we will change the names, argument lists and 
return types as needed.  All they reserve is slots in the vtable.

I'd like to reserve some space (a couple of void* members) and 
some virtuals in basic_streambuf as well.   I suppose I can 
prepare those patches myself, you needn't bother.
