miniupnpd/upnppermissions.c: disable match_permission_internal()
miniupnpd/getifaddr.c: fix getifaddr_in6()

-1 is returned if no address is found
miniupnpd/getifaddr.c: getifaddr_in6() only return IPv4 address when IPV6 disabled

see if it can help for issue #62
pcp/CheckAddress() is likely to need more changes.
