This is done adding a new field in each mbuf storing the size of this private area. Another option would have been to store that in the mbuf pool private info, but as we have enough room in mbuf, it's faster to have it in the mbuf. The series also removes the limitation that rte_pktmbuf_clone() is only allowed on direct (non-cloned) mbufs.
