Done: implemented One-shot multicast DNS queries for ".local" names when setting LWIP_DNS_SUPPORT_MDNS_QUERIES==1

Simple query is easy to add, but for a more complete implementation, we'd need caching (which is used for bandwidth limitation).

References Internet Draft: draft-cheshire-dnsext-multicastdns-08.txt (http://datatracker.ietf.org/doc/draft-cheshire-dnsext-multicastdns/)


Enables the simplest 'multicast' dns client by identifying requests for multicast domain names (eg domain names ending in .local) and submitting the dns query to 224.0.0.251:5353

Refer to section 6.1 in above document.

This functionality would enable LWIP applications to resolve .local host names on LANs without the need to update or manage a DNS server.

Macs, Windows and Linux machines can be easily configurered to respond to mDNS queries.
