This routine enables a more general-purpose task watchdog: tasks can individually
feed the watchdog and the watchdog will bark if one or more tasks haven't fed the
watchdog within the specified time. Optionally, the idle tasks can also configured
to feed the watchdog in a similar fashion, to detect CPU starvation.

This uses the TIMERG0 WDT.
