Add the most straightforward 'get' functions required for anaconda. These are the ones that return simple uint64_t values. The other more complex ones involve the lv_attr bits. These will come in a separate patch series since each lv_attr bit will be returned in a separate API instred of returning the string and requiring the user to parse it.
