OpenVPN for Android uses config stdin to avoid writing the config file containing private keys to 'disk'. However using stdin means that config cannot be reread using SIGHUP. While there might be other corner cases that trigger SIGHUP, this is an obvious one, so we error out if we detect this misconfiguration.
