Invoke additional MAC entry points when an mbuf packet header is copied to another mbuf: release the old label if any, reinitialize the new header, and ask the MAC framework to copy the header label data. Note that this requires a potential allocation operation, but m_copy_pkthdr() is not permitted to fail, so we must block. Since we now use interrupt threads, this is possible, but not desirable.
