Use formal API for ActivityThread to set proxy
Add setHttpProxyConfiguration to the public API, and use
ConnectivityManager APIs from ActivityThread (instead of hidden APIs) to
get/set the proxy for an app process.
The default proxy is now initialized with getDefaultProxy instead of
getProxyForNetwork(null); this should not make a difference, as nothing
should have called bindProcessToNetwork at that point yet.
