Merge: * use upstream servers directly for the internal DNS resolver Close #1212 * Server.Start(config *ServerConfig) -> Start() + Server.Prepare(config *ServerConfig) + Server.Resolve(host string) + Server.Exchange() * rDNS: use internal DNS resolver - clients: fix race in WriteDiskConfig() - fix race: move 'clients' object from 'configuration' to 'HomeContext' Go race detector didn't like our 'clients' object in 'configuration'. + add AGH startup test . Create a configuration file . Start AGH instance . Check Web server . Check DNS server . Wait until the filters are downloaded .
