CORBA23 — Missing equality for DynAny

Summary: Type DynAny has no equality operator. This makes it impossible
to determine whether or not two DynAnys contain the same value, unless
I am prepared to recursively iterate over all of a DynAny"s components
to determine whether they are equal. This is rather inconvenient.

I would suggest to add a new operation to DynAny:

boolean equal(in DynAny da);

added comparison operator
