- Add _tracer_app_gnb and t_tracer_app_ue apps to common/utils/T/tracer/Makefile - Add Data collection Service for gNB: common/utils/T/tracer/t_tracer_app_gnb.c - Add Data Collection Service for UE: common/utils/T/tracer/t_tracer_app_ue.c - Add Shared memory configuration (common/utils/T/tracer/shared_memory_config.h), since We will have too much memory consumption on the stack if the T-tracer is not fast enough to process the traces or if we have too much traces. As a result, tracers start to capture data, write data in shared memory, then close the T-Tracer after getting the recording of N slots - Support the operation of : COnfig, Record, and Stop - Poll from Socket and not use get_events to mitigate long-time waiting if there is no data in buffer or the UE is already released or crashed - Add extra offset to improve data sync
