#373 tau_requestEcspConfirm callback not working

[Stefan Bender]

The callback function ecspConfRepMDCallback() in tau_ctrl.c is registered with a listener in tau_initEcspCtrl() instead of the request callback in tau_requestEcspConfirm().
This results in tau_requestEcspConfirmReply() not working as intended and requires the application to add its own callback function.
