  Modified files:
    sys/net              bpf.h 
    sys/sys              mbuf.h 
  Log:
  Add a new macro M_ASSERTVALID which ensures that the mbuf in question
  is non-free.  (More checks can/should be added in the future.)
  
  Use M_ASSERTVALID in BPF_MTAP so that we catch when freed mbufs are
  passed in, even if no bpf listeners are active.
  
  Inspired by a bug in if_dc caught by Kenjiro Cho.
