Introduce QNetworkConnection/Status/Monitor

Private classes to replace broken or even not working at all 'session management'
and 'bearer manager' (on at least two major platforms we support). This
implementation is macOS/iOS-specific and uses SystemConfiguration framework,
or more precisely SCNetworkReachability's part of it.
