Subject: * split off lookup.h and publish.h from core.h * implement wide-area
 DNS-SD * if multiple clients query the same records, only start the query
 packet sequence once * implement recursive CNAME queries * add support for
 resolving services without TXT or A/AAAA records * enlarge resolving timeouts
 to 5s * implement new browse/resolving events CACHE_EXHAUSTED/ALL_FOR_NOW *
 add support for resolving services without name. (i.e. for normal SRV
 records)
