QNAM HTTP: Fix readBuffer maximum size.
QHttpNetworkReply has now a throttled mode. If this is activated, it will only read HTTP body when its internal buffer is empty. This means that QNetworkReply.setReadBufferSize() can finally be used for bandwidth limiting. Thanks to David Faure for helping out. Reviewed-By: Peter Hartmann
