Teach DownloadManager about network policy.

Now network access is determined by using getActiveNetworkInfoForUid()
which uses BLOCKED to indicate that network should be rejected for
the requesting UID.  While download in progress, watch for any policy
changes that should trigger pause.

Also check NetworkInfo.isConnected() for correctness.
