if an xrun occurs, flash "Audio I/O Error" label and send the number of dropped samples to the "pd-xrun" symbol.

Currently, xruns only flash the "Audio I/O Error" message. Now we also send the number of dropped samples to "pd-xrun", so the user can handle it.
Xruns are reported from the audio callback with the
sys_reportxrunfunction, which just increments an atomic counter. Insched_idletaskwe atomically check and reset the counter and take the appropriate action.
