  Modified files:
    sys/kern             uipc_sockbuf.c 
  Log:
  sbappendcontrol() was improperly setting sb_lastmbuf, creating a possible
  mbuf leak and/or sb_cc count mismatch.  The passed mbuf 'm' is a chain,
  not a single mbuf, and must be iterated through to locate the last mbuf.
  
  Optimize sbappend().  M_EOR is always set in the last mbuf and the sockbuf's
  sb_lastmbuf and sb_lastrecord fields can be used instead of iterating
  through all the mbufs in the sockbuf.  Only UNIX domain stream sockets used
  this function.  Normal TCP connections use the already-optimized
  sbappendstream() call.
  
  Properly propogate M_EOR in sbappendcontrol() and sbappendaddr().
  
  Do various code and comment cleanups.
