Subject: mdns: add the new openwrt mdns daemon

this is still wip, you can use the following ubus calls.

ubus call mdns scan	# triggers a scan
ubus call mdns browse	# look at the currenlty cached records
ubus call mdns hosts	# look at the currenlty cached hosts

TODO
- ipv6, currenlty AAAA records are handled but only on v4 sockets
- finish the service announce code
