util_init_recur_task_sync

Initializes properties of a recurring vtodo, like normalizing the Due date and eventually the Start date.

The function does nothing when the vtodo is not recurring.

The function doesn't change LAST-MODIFIED neither the SEQUENCE property, it's up to the caller to do it.

Note the cal_client, cancellable and throws is used only for timezone resolution. The function doesn't store the vtodo to the cal_client, it only updates the vtodo component.

Parameters:

vtodo	a VTODO component
cal_client	an Client to which the vtodo belongs
cancellable	optional Cancellable object, or null

Returns:

Whether succeeded.
