//version history
// 6  add PositionTect bitmap parameter in MOLR_BEGIN_REQ, add session_id in MTLR_BEGIN_IND and MTLR_BEGIN_RSP
// 7  change version's type from short to int to avoid unaligned access
// 8  add 4 Session IND messages
// 9  extend requestor_id and client_name from 128 bytes to 160 bytes
// 10 define LPP UP SWIP <-> LPP CP message ID (no struct definition, uses raw data)
// 11 add AGPS_MD_TYPE_MTLR_BEGIN_2_IND and agps_md_mtlr_begin_2_ind struct
// 12 add supporting eutran band list in sim_info_rsp
// 13 add session_id in agps_md_auto_mtlr_response_ind struct
// 13.2 add AGPS_MD_TYPE_SIM_INFO_IND for MD to report SIM_INFO when it is boot up complete, AP CCCI driver should keep the data sent from MD when AP/AGPS does not open CCCI yet
// 13.3 add AGPS_MD_TYPE_LPP_PEER_OTDOA_RESET_UE_STORED_POS_REQ for SUPL LPP session to delete OTDOA data in MD side when A-GPS session is finished
// 13.4 add AGPS_MD_TYPE_MDT_SUPL_DONE_RSP and AGPS_MD_GPS_OPEN_IND_TYPE_MDT for MDT session
// 13.5 add AGPS_MD_TYPE_LOCATION_NTF to sync the latest location to MD side
// 13.6 add support_lpp_otdoa_nbr_cell_list in agps_md_sim_info_rsp and agps_md_sim_info_ind for LPP inter-freq (only on LPP, no implementation on LBS)
// 13.7 add supl flow indication
// 13.8 add AGPS_MD_TYPE_CP_SERVICE_CONFIG_NTF to do CP on/off in runtime, this should be used in Titan's project only
// 13.9 add CP service config in agps_md_sim_info_req struct
// 13.10 add AGPS_MD_TYPE_MODEM_REBOOT_IND when LBS task is initiated or flight mode on/off
// 13.11 add the huge data transfer
// 13.12 add support_location_settings and AGPS_MD_TYPE_LOCATION_SETTINGS_NTF
// 13.13 move agps_md_huge_data_type from huge_data_transfer.h to agps_md_interface.h
// 13.14 re-name agps_md_huge_data_type to agps_md_huge_data_msg_id
// 13.15 add reject_non911_nilr_enable for LGE VZW requirement
// 13.16 add battery_percentage in agps_md_sim_info_req struct to sync the battery percentage per 5% to MD/LBS
// 13.17 add support_ue_rx_tx_sup_tdd_r13 in agps_md_sim_info_rsp
// 13.18 add NR positioning
// 13.19 add location source in AGPS_MD_TYPE_LOCATION_NTF
// 13.20 add support_md_time_sync and AGPS_MD_HUGE_DATA_TYPE_MD_TIME_XXX
