fix re-opening log files after deleting or moving them

With the patch attached, syslogd correctly re-opens log files. The current code uses one global last-logged timestamp for all log targets. If a message is to be logged to multiple log files, the global last-logged timestamp is compared to the current system time. If there is a difference of at least one second, the log file is re-opened and the timestamp is updated. However, because of the timestamp update, all subsequent log files are _not_ re-opened even if they need to.

The patch attached uses a per-log-target timestamp to overcome this bug.
