integration of LCID for NB-IoT (MAC/defs_nb_iot.h), complete the thread for the phy_procedures_TX (Schedule_response) and other minor changes

review of PHY_Config_t structure parameters for FAPI-like approach. Implement the FAPI required parameters and adding some extras in separate structure. Code compile

Merge branch 'develop-nb-iot-mac' of https://gitlab.eurecom.fr/oai/openairinterface5g into develop-nb-iot-mac

Sincronization with Nick work

Implementation of configuration data structures following FAPI-like approach. Some parameters seem to be non implemented in FAPI (for the moment addedd manually). Cleaning of some part of RRC code. Code compile.

Added new files for IF-module purposes (still to complete), review some configuration procedure for FAPI-like approach. Code compile

Merge branch 'develop-nb-iot-mac' of https://gitlab.eurecom.fr/oai/openairinterface5g into develop-nb-iot-mac

Sincronization with NICK work on the same branch

First implementation of FAPI-like P5 configuration for the PHY layer. PHY_Config_t structure, modified NB_rrc_mac_config_req_eNB for triggering the IF_Module PHY_config_req function. Some common config. and all the dedicated configuration are missed

Merging mac branch to RRC branch for IF-Module implementation(still not completed). Solve some bugs. Now move to mac branch for continue implementation

Conflicts:
	openair1/PHY/impl_defs_lte_nb_iot.h

adding PHY_Config structure for FAPI-like PHY configuration, still to finish the function call. The code compile
