Subject: Allow socket events processing with a foreign event loop on Windows

While a native dialog is open, the application message queue is
handled by the native event loop which is external to Qt. In this
case, QEventDispatcherWin32::processEvents() does not run and socket
notifiers will not be activated. So, this patch moves the notifier
activation code into the window procedure, which enables socket
event processing with native dialogs.
