xbt_cfg_set_vargs() and xbt_cfg_set() now handle only one variable at a time (they used to deal with NULL-terminated lists of arguments, but it was error-prone); Explicit another argument before the vaargs so that module setting function can pass their vaargs to the generic ones (the cfg set is implicit and don't need to be passed as argument in modules, so we can't va_start() on it); fix some error handling errors :-/
