Subject: erlsrv: gracefully stop emulator on Windows shutdown
Windows will send the SERVICE_CONTROL_SHUTDOWN event to the service control
handler when shutting down the system. Instead of ignoring the event, erlsrv
will now invoke the stop action. Likewise, the Erlang emulator (and it's port
drivers) must not quit upon reception of the CTRL_SHUTDOWN_EVENT event in the
console control handler.
