Give classes with virtual methods virtual protected d'tors instead of non-virtual public implicit d'tors.
Was originally:
Replace public nonvirtual destructors in classes with virtual members
with protected nonvirtual destructors where possible, and with
public virtual destructors where destruction of a derived class occurs.
(chrome/browser/[a-m]* only)
(Part 4 of http://www.gotw.ca/publications/mill18.htm
has a rationale for why public nonvirtual destructors in classes with
virtual members is dangerous.)
