  Inherit privately from angle::NonCopyable.
  
  Make all inheritance from angle::NonCopyable private so the compiler
  complains about this (admittedly unlikely) code:
  
    class Foo: angle::NonCopyable {
        virtual ~Foo() { ... }
    };
    angle::NonCopyable *p = new Foo;
    delete p;
  
  In the above code ~Foo() is not called, only ~NonCopyable(), because the
  latter is not virtual.  Making it virtual would add overhead to all derived
  classes which don't already have a virtual method.
  
  Also tighten access in NonCopyable, because we can.
