++/*************************************************
++* Handle a check for previously-seen *
++*************************************************/
++
++/*
++ACL clauses like: seen = -5m / key=$foo / readonly
++
++Return is true for condition-true - but the semantics
++depend heavily on the actual use-case.
++
++Negative times test for seen-before, positive for seen-more-recently-than
++(the given interval before current time).
++
++All are subject to history not having been cleaned from the DB.
++
++Default for seen-before is to create if not present, and to
++update if older than 10d (with the seen-test time).
++Default for seen-since is to always create or update.
++
++Options:
++ key=value. Default key is $sender_host_address
++ readonly
++ write
++ refresh=<interval>: update an existing DB entry older than given
++ amount. Default refresh lacking this option is 10d.
++ The update sets the record timestamp to the seen-test time.
++
++XXX do we need separate nocreate, noupdate controls?
++
++Arguments:
++ arg the option string for seen=
++ where ACL_WHERE_xxxx indicating which ACL this is
++ log_msgptr for error messages
++
++Returns: OK - Condition is true
++ FAIL - Condition is false
++ DEFER - Problem opening history database
