Summary: Replace inefficient busy wait loop with UDP/IP loopback socket.

Initial Comment:
Here are some patches for win32-service which eliminate the messy busy loop that
polls the hStopEvent with a zero timeout.  Instead of using a Windows event,
these patches create a UDP/IP socket bound to the loopback interface which can
be used in ruby''s green  threads event loop.  I believe this is a much
cleaner and more efficient mechanism than the WIndows event flag since it allows
the ruby thread to block until there''s really a control event from the
WIndows service manager.

I also include a hCtrlEvent event flag which can be used by ruby win32 services
which must wait for control events.  This event handle is accessible via the
daemon.event_handle method.  Note that the hCtrlEvent is not used by the
daemon.c logic, it''s merely an event which can be used by the Daemon
subclass.
