    sys/kern             uipc_mbuf.c 
  Log:
  Fix a bug in the mbstats accounting.  m_mbufs was being decremented for
  normal mbufs converted to clustered mbufs, but in fact it should not be
  because we decrement it properly when the normal-mbuf-with-cluster is
  freed.
  
  Change most of the m_getl()'s back to m_get()'s or m_gethdr()'s in order
  to guarentee that the mbuf does NOT have a cluster associated with it
  since we are going to try to share the old mbuf's cluster later on
  (in m_copym()).  This bug was causing the system to run out of mbuf
  clusters.
  
  Add a number of assertions for correct operation.
