Merge changes from topic "ril-split" into cuttlefish-testing

* changes:
  Minimal cleanup of the ril code for P compatibility
  Added 1.4 setDataProfile and setInitialAttachApn
  Add default implementation for carrier lock commands in IRadio 1.4
  Populate radio access family
  Add default implementation of enableModem for cuttlefish
  VTS test for IRadio 1.3 setSystemSelectionChannels
  Add default impl for emergencyDial
  Add default impl for getSignalStrength_1_4 and backward compatibility for getIccCardStatus
  Add cuttlefish default implementation for networkTypeBitmap
  Add default implementation of getModemStackStatus for cuttlefish
  Add StartNetworkScanV1_4 Impl
  Fork legacy ril into cuttlefish to support radio hal 1.4.

+ * 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_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.
+ *
+ * RIL_VERSION = 15 : New commands added:
+ *                    RIL_UNSOL_MODEM_RESTART,
+ *                    RIL_REQUEST_SEND_DEVICE_STATE,
+ *                    RIL_REQUEST_SET_UNSOLICITED_RESPONSE_FILTER,

+ *                    RIL_REQUEST_SET_CARRIER_INFO_IMSI_ENCRYPTION,
+ *                    RIL_UNSOL_CARRIER_INFO_IMSI_ENCRYPTION
+ *                    The new parameters for RIL_REQUEST_SETUP_DATA_CALL,
+ *                    Updated data structures: RIL_DataProfileInfo_v15, RIL_InitialAttachApn_v15
+ *                    New data structure RIL_DataRegistrationStateResponse,
+ *                    RIL_VoiceRegistrationStateResponse same is
+ *                    used in RIL_REQUEST_DATA_REGISTRATION_STATE and
+ *                    RIL_REQUEST_VOICE_REGISTRATION_STATE respectively.
+ *                    New data structure RIL_OpenChannelParams.
+ *                    RIL_REQUEST_START_NETWORK_SCAN
+ *                    RIL_REQUEST_STOP_NETWORK_SCAN
