  Log:
  Rename m_getm() to m_getm2() and rewrite it to allocate up to page sized
  mbuf clusters.  Add a flags parameter to accept M_PKTHDR and M_EOR mbuf
  chain flags.  Provide compatibility macro for m_getm() calling m_getm2()
  with M_PKTHDR set.
  
  Rewrite m_uiotombuf() to use m_getm2() for mbuf allocation and do the
  uiomove() in a tight loop over the mbuf chain.  Add a flags parameter to
  accept mbuf flags to be passed to m_getm2().  Adjust all callers for the
  extra parameter.
