tools: Allow patlooptest to activate and handle buffer events

Browse Source 
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.
