+/* NAME
+/* cleanup_state 3
+/* SUMMARY
+/* per-message state variables
+/* SYNOPSIS

+/* CLEANUP_STATE *cleanup_state_alloc(src)

+/* 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.
