Unify SIB container handling by introducing a typed SIB enum and storing
SIB payloads as byte_array_t across common NR types, F1AP helpers, MAC,
and RRC DU setup code.
Changes:
- Include byte_array support in nr_common.h, add nr_sib_type_t (NR_SIB_1–NR_SIB_21),
and change nr_SIBs_t to hold only nr_sib_type_t SIB_type.
- Switch f1ap_sib_msg_t in f1ap_messages_types.h to use a byte_array_t SI_container
instead of raw pointer and length fields.
- Update F1AP encode/decode, equality, copy, and free helpers in
f1ap_interface_management.c to work on SI_container.buf / SI_container.len and
use eq_byte_array, copy_byte_array, and free_byte_array.
- Adapt F1AP tests in f1ap_lib_test.c to build and inspect SIB containers via
SI_container.buf and SI_container.len.
- Replace magic SIB numbers with nr_sib_type_t values in gnb_config.c
(get_sys_info and fill_du_sibs) to validate and configure DU SIBs.
- Rework nr_mac_configure_other_sib in NR_MAC_gNB/config.c to decode SIB2
from a byte_array_t container, fix freeing by releasing the decoded sib2 on
failure, and use NR_SIB_2 / NR_SIB_19 for CU/DU SIB selection.
- Add an add_si_msg helper in rrc_gNB_du.c and refactor the SIB2 branch of
rrc_gNB_process_f1_setup_req to populate cell->SI_msg from encoded local
byte array while iterating SIBs with FOR_EACH_SEQ_ARR.

Add F1AP Paging library and new message type to follow the existing F1AP
library pattern and to support multi-cell paging and both RAN UE (I-RNTI)
and CN UE (5G-S-TMSI) paging identities at the library level per TS 38.473.
* New library (f1ap_paging.c/h, f1ap_lib_includes.h, CMakeLists.txt)
- Implement encode/decode/copy/eq/free for F1AP Paging (procedure 9.2.6).
- Add ASN.1 includes for Paging, PagingIdentity, CN/RAN UE identities.
- Enables unit testing of Paging enc/dec in f1ap_lib_test.c.
* New types in f1ap_messages_types.h (existing f1ap_paging_ind_t unchanged)
- f1ap_paging_t: UE Identity Index, paging identity (union + type enum),
optional paging_drx, paging_priority, paging_origin, and paging_cells[].
- f1ap_paging_cell_item_t, f1ap_paging_identity_type_t, f1ap_paging_identity_t
for multi-cell list and RAN/CN identity discrimination.
- Paging Origin IE is optional per F1AP 8.7.1.2.
Tests: test_f1ap_paging() roundtrip and copy for CN UE (5G-S-TMSI) and
RAN UE (I-RNTI) cases, with optional IEs.
* Commit applies to Setup Request, CU/DU Configuration Update
* Set standard compliant max number of cells per DU
* Allocate large lists on the heap to prevent stack overflow
due to the large size
* Update relevant free functions
* Also, fix bug in eq_f1ap_cu_configuration_update
Also, improve comments in struct definition.
This field will be adopted to trigger cgc encoding at DU,
according to the specs (see subsequent commit for details).
Changes:
- Add gNB_DU_Configuration_Query field to f1ap_ue_context_mod_req_t
- Implement encoding/decoding
- Add to cp, eq, and free functions for the new field
- Update tests to include the new field

Reintroduce separate message types to simplify the encoding/decoding,
including shorter names. The old types will be removed once everything
has been migrated to the new encoder/decoder, which should ensure that
everything is properly migrated to the unit-tested encoder/decoders.
Also, for each type of F1 message (F1 UE context setup request,
response, modification request, ...) introduce a separate type to avoid
to mistakenly use wrong fields, which can lead to bugs. In this regard,
the DL PDCP SN bit size in the DRB-ToBeSetup list of the UE context
setup request is optional, as it will also be used in the UE context
modification request DRB SetupMod list (which avoids quite some code
duplication). The encoder checks that this IE is present, though.
