Currently, when allocating memory for data, size of tld_data_u->start is not taken into account. This may cause OOB access. Fixed it by adding the non-flexible array part of tld_data_u. Besides, explicitly align tld_data_u->data to 8 bytes in case some fields are added before data in the future. It could break the assumption that every data field is 8 byte aligned and sizeof(tld_data_u) will no longer be equal to offsetof(struct tld_data_u, data), which we use interchangeably.
