i would prefer to call sip_trace() up front in the script in order to
avoid calling it many places. currently, however, looks like setting of
traced_user_avp after sip_trace() is called has no effect.
how about if i add a module var delayed_avp_trace (or something) so that if
it has value 1, trusted_user_avp value is checked when the message is
actually stored by sip_trace_store_db function?
