Add support for RESOLV_TRY_ALL_SERVERS

Queries with the flag set will try all resolvers.

 - If a resolver returns NOERROR and has replies, its response is used.
 - If all resolvers return another rcode or empty replies (NODATA), the
   first reply will be used.
 - If queries time out, the resolver will apply the usual retry strategy
   to that server. If all queries time out on one of the servers, a
   timeout will be returned.
