    tools: Allow patlooptest to activate and handle buffer events
    
    The new buffer events code introduced in revision 9905 gives userspace
    processes an interface to activate detection of buffer over and underflows.
    This change allows patlooptest to take advantage of that feature to better
    inform users of the cause of pattern errors.
