Generates a number of new one time keys. If the total number of keys stored
* by this account exceeds max_number_of_one_time_keys() then the old keys are
* discarded. Returns olm_error() on error. If the number of random bytes is
* too small then olm_account_last_error() will be "NOT_ENOUGH_RANDOM".
