description:
Marking different external pointer with unique tag.
An external value has an arbitrary raw pointer associated with it.
External values with different prototypes have different C-level
structures. To ensure that only appropriate structures are fetched
by njs_vm_external() the unique tag has to be provided during
creation of external values.
