  15 /*      CLEANUP_STATE *state;
  16 /* DESCRIPTION
  17 /*      This module maintains about two dozen state variables
  18 /*      that are used by many routines in the course of processing one
  19 /*      message.
  20 /*
  21 /*      cleanup_state_alloc() initializes the per-message state variables.
  22 /*
  23 /*      cleanup_state_free() cleans up.
