Hi

I've added the fix from yesterday to CVS HEAD which checks all timers  
if they are elapsed
in NutTimerProcessElapsed but added a nutTimerStopped flag to trigger
checking only when a timer was stopped. this should remove additional
overhead to one list search iff at least one timer was stopped.
all this is done in normal context (not in a critical section)
