  Log:
  Go through the loopback code with a broom..
  Remove lots'o'hacks.
  looutput is now static.
  
  Other callers who want to use loopback to allow shortcutting
  should call the special entrypoint for this, if_simloop(), which is
  specifically designed for this purpose. Using looutput for this purpose
  was problematic, particularly with bpf and trying to keep track
  of whether one should be using the charateristics of the loopback interface
  or the interface (e.g. if_ethersubr.c) that was requesting the loopback.
  There was a whole class of errors due to this mis-use each of which had
  hacks to cover them up.
  
  Consists largly of hack removal :-)
