openairinterface5g/openair2/RRC/NR_UE/rrc_defs.h
Guido Casati c9e82d6a12 Refactor UE (RRC/MAC): typed NR_MAC_RRC_START_RA for T300 and re-estab 
RRC starts random access via NR_MAC_RRC_START_RA with an explicit
cause. RA trigger is no longer piggybacked on NR_MAC_RRC_CONFIG_RESET.
T300 expiry and RRC re-establishment are the call sites switched in this
commit. MAC handles setup/T300 and re-establishment paths in
nr_mac_start_ra().

Changes:
- Add nr_mac_rrc_types.h (nr_mac_ra_start_cause_t)
- Add nr_mac_rrc_start_ra_t in rrc_messages_types.h
- In rrc_UE.c, add nr_rrc_trigger_mac_ra(), call it from
  handle_t300_expiry and nr_rrc_initiate_rrcReestablishment
- In config_ue.c:
  - add nr_mac_start_ra() entry point with causes switch
  - add nr_rrc_mac_start_ra() handler
  - remove T300_EXPIRY, RE_ESTABLISHMENT reset handling
    in nr_rrc_mac_config_req_reset, now delegated to
    nr_mac_start_ra
- mac_defs.h: drop T300_EXPIRY from NR_UE_MAC_reset_cause_t
