Pervious Permit/Deny config parser return value change, causes sccp reload to restart all devices every time. Because it is difficult evaluate if ha changed between reloads. Instead of setting alreadySetEntries on SCCP_CONFIG_CHANGE_CHANGED it is now set on \!SCCP_CONFIG_CHANGE_INVALIDVALUE, which yields the correct behaviour (though less precise)
