Add simple measure restricting event access using pmstore.
This adds a third parameter to each line in the config file,
saying whether or not a store is required to access the event
stream. logger_store PDU callback added to implement this.
Some code clarifications made - rename head to queue so I can
better grok the per logfile tailq use, use TAILQ_NEXT in some
places where it was effectively open coded, consistently name
"sts" return code variable throughout.
