  Modified files:
    sys/kern             uipc_mbuf.c 
  Log:
  Introduce support for Mandatory Access Control and extensible
  kernel access control.
  
  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.
