- with this it's also possible to talloc_free() the ndr_pull structure
and talloc_steal(ndr->current_mem_ctx); to fetch the whole data of the hierachical tree
- if the toplevel struct is a valid talloc pointer it's also possible to use
NDR_PULL_SET_MEM_CTX(ndr, mem_ctx); to the the toplevel pointer with the struct pointer
(NOTE: no callers are using this yet, but they shortly will)
