DO NOT MERGE Add new info functions to resolver for use by Netd.

android_net_res_stats_get_info_for_net returns the current name servers, search
domains, parameters and stats for the given network ID.

android_net_res_stats_aggregate provides statistics such as errors counts from
the raw stats data reported by android_net_res_stats_get_info_for_net.

android_net_res_stats_get_usable_servers uses the data returned by
android_net_res_stats_aggregate to determine which of the servers are
considered valid or broken by the resolver.
