This is pretty easily scriptable with a handful of lines of Python. Loop through each of the constraints of each of the bones in your armature, looking for Stretch To or Child Of constraints and running the reset operator.

And if you want to make it fancy, wrap that all in its own operator and pre-pend a button for it in the Bone Constraints panel.
