[NaCl SDK] nacl_io: Add a few new pepper_interface classes, some docs.

I've added two new PepperInterface-derived classes:

* PepperInterfaceDelegate, which allows you to delegate Get*Interface()
  to a different PepperInterface object, e.g.

    FooInterfaceDelegate foo;
    PepperInterfaceDelegate delegate;
    delegate.SetCoreInterface(foo.GetCoreInterface());

* PepperInterfaceDummy, which returns NULL for all Get*Interface()
  functions.  This way you can only implement the interface getters you
  are interested in.

I've also added some documentation.

BUG=none
