eo_lifecycle: on log level info (3), show leaked objects. 

Since we keep a log of created and deleted objects, we can walk the
log and see which were leaked. As this is expensive, do only if log
level is greater than 3 (INFO, DEBUG...), with backtrace of object
creation being displayed as backtrace if running as level 4 (DEBUG).
