[CU] Add dup_instance function to libcmpiutil
It appears there are some situations where we have to duplicate an instance; this seemed
like the kind of thing that would belong in libcmpiutil.
Changes from #1 to #2:
cu dup_instance returns instance, sets status using pointer
cu_dup_instance copies all properties
