/* NAME
/* cleanup_state 3
/* SUMMARY
/* per-message state variables
/* SYNOPSIS
/* #include "cleanup.h"
/*
/* CLEANUP_STATE *cleanup_state_alloc(void)

/* void cleanup_state_free(state)
/* CLEANUP_STATE *state;
/* DESCRIPTION
/* This module maintains about two dozen state variables
/* that are used by many routines in the course of processing one
/* message.
/*
/* cleanup_state_alloc() initializes the per-message state variables.
/*
/* cleanup_state_free() cleans up.
