Merge: * use upstream servers directly for the internal DNS resolver

Browse source 
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
    . Stop and cleanup
* move module objects from config.* to Context.*
* don't call log.SetLevel() if not necessary
    This helps to avoid Go race detector's warning
* ci.sh: 'make' and then run tests

    Revert: * stats: serialize access to 'limit'

    Use 'conf *Config' and update it atomically, as in querylog module.
    (Note: Race detector still doesn't like it)
