   * RIL version.
   * Value of RIL_VERSION should not be changed in future. Here onwards,
   * when a new change is supposed to be introduced  which could involve new
   * schemes added like Wakelocks, data structures added/updated, etc, we would
   * just document RIL version associated with that change below. When OEM updates its
   * RIL with those changes, they would return that new RIL version during RIL_REGISTER.
   * We should make use of the returned version by vendor to identify appropriate scheme
   * or data structure version to use.
   *
   * Documentation of RIL version and associated changes
   * RIL_VERSION = 12 : This version corresponds to updated data structures namely
   *                    RIL_Data_Call_Response_v11, RIL_SIM_IO_v6, RIL_CardStatus_v6,
   *                    RIL_SimRefreshResponse_v7, RIL_CDMA_CallWaiting_v6,
   *                    RIL_LTE_SignalStrength_v8, RIL_SignalStrength_v10, RIL_CellIdentityGsm_v12
   *                    RIL_CellIdentityWcdma_v12, RIL_CellIdentityLte_v12,RIL_CellInfoGsm_v12,
   *                    RIL_CellInfoWcdma_v12, RIL_CellInfoLte_v12, RIL_CellInfo_v12.
   *
   * RIL_VERSION = 13 : This version includes new wakelock semantics and as the first
   *                    strongly versioned version it enforces structure use.
   * RIL_VERSION = 14 : New data structures are added, namely RIL_CarrierMatchType,
   *                    RIL_Carrier, RIL_CarrierRestrictions and RIL_PCO_Data.
   *                    New commands added: RIL_REQUEST_SET_CARRIER_RESTRICTIONS,
   *                    RIL_REQUEST_SET_CARRIER_RESTRICTIONS and
   *                    RIL_UNSOL_PCO_DATA
