* We modify connection management such that we now use more specific connection types for {content, non-content, socket process} connections. * We attach a native counterpart to the `GeckoProcessManager.ConnectionManager` instance that listens for app foreground, app background, and when the socket process is enabled, network state events. * On app background, all non-content processes are assigned BACKGROUND priority. Even though backgrounding the app will cause Android to drop all child processes' priority regardless of our priority settings, we still do this as to indicate to Android that these processes are relatively less important than our parent process. * When the socket process is enabled, we drop its priority when we detect that we have no network connectivity. Note that the network management code does the Right Thing if network connectivity changes while our app was in the background: we receive the network state change event once we return to foreground, therefore we do not need to do any special handling ourselves.
