gbproxy: Track SGSN and BSS TLLI/PTMSI separately
This patch separates BSS side from SGSN side TLLI/PTMSI tracking. When
TLLI/PTMSI patching is not enabled, the corresponding states shall be
identical. The TLLI/PTMSI state has been moved into the struct
gbproxy_tlli_state and is used twice in gbproxy_tlli_info.
Since the state handling for uplink and downlink messages is
diverging, gbprox_update_state() is replaced by two functions
gbprox_update_state_dl/gbprox_update_state_ul and
gbprox_process_bssgp_message() is replaced by
gbprox_process_bssgp_dl/gbprox_process_bssgp_ul.
