From 04c841190f0ce5e89724d9221904c60e75988727 Mon Sep 17 00:00:00 2001

Subject: [PATCH] - Pass "module_id" to the two log-related settings that are
 no longer   global. - Added a "restart" arg to log_init() that lets us
 request that logging   be reinitialized if the log-file/syslog-facility
 params changed.
