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.

Still does not run, just compiles.

The ERTS internal system block functionality has been replaced by
new functionality for blocking the system. The old system block
functionality had contention issues and complexity issues. The
new functionality piggy-backs on thread progress tracking functionality
needed by newly introduced lock-free synchronization in the runtime
system. When the functionality for blocking the system isn't used
there is more or less no overhead at all. This since the functionality
for tracking thread progress is there and needed anyway.

All uses of the old deprecated atomic API in the runtime system
have been replaced with the use of the new atomic API. In a lot of
places this change imply a relaxation of memory barriers used.
