Subject: network.*: - addr_resolv(_or_parse_ip)(): added an optional parameter
 to return both an IPv6 and an IPv4 address if requested address family was
 AF_UNSPEC - logging of unhandled packets

DHT.c:
- bootstrap_from_address(): use the additional return from addr_resolv_or_parse_ip() to bootstrap in both network types at once

Lossless_UDP_testclient.c:
- main(): adapt to signature change of addr_resolve()

Messenger.c. LAN_discovery.h:
- lost a htons(), readded
- moved LAN_DISCOVERY_INTERVAL #define into LAN_discovery.h

LAN_discovery.c:
- added IPv4-in-IPv6 local address test
