[AGENT++] Configuring community strings

either you're using agent++ with version lower than 3.5.21, or you're
configuring some of these tables.

The code below from the atm_mib example adds a mapping from community
PubliC to securityname PubliC (co is used twice in set_row()!):

	OctetStr co("PubliC");
	MibTableRow* row = snmpCommunityEntry::instance->
	    add_row(Oidx::from_string(co, FALSE));
	OctetStr tag("v1v2cPermittedManagers");
	snmpCommunityEntry::instance->
	    set_row(row, co, co,
		    reqList->get_v3mp()->get_local_engine_id(),
		    "", tag, 3, 1);

Then you have to configure the VACM to allow access for the PubliC user
(vacm->addNewGroup, vacm->addNewAccessEntry, vacm->addNewView)
