  Replace non-copyable macro with a helper class.
  
  This class provides a simpler scheme for blocking default copy
  and assignment operators. It also reduces the amount of code
  needed since it's inherited to child classes. This also fixes
  the conflict between our macro and the same-named macro in
  Chromium code.
