Guido Casati e27f8c24cf Refactor (F1AP/RRC): convert SIB containers to byte_array_t
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.

- all RAN code, CI code, configuration files, dockerfiles, in CSSL v1.0
- all deployment code (openshift, charts, ancillary files like shell
  scripts), in MIT
- documentation in CC-BY-4.0
- exceptions might apply and are listed in NOTICE
- there is a new LICENSES folder with all licenses
- CONTRIBUTIONS.md has been updated accordingly

For automated changes based on OAI PL v1.1:

Guido Casati 563a0cfa61 Refactor: unify equality-check macros across protocol libs
This commit centralizes equality-check behavior and removes duplicated
macro implementations across protocol stacks.

Major changes:
- add `common/utils/eq_check.h` with shared `_EQ_CHECK_*`,
  `EQ_CHECK_GENERIC`, and optional-IE pointer helpers
- replace E1AP/F1AP/NAS local equality macros and call sites with
  the shared helpers
- remove duplicated layer-specific error/equality macro definitions from
  common headers and switch includes to `eq_check.h`
- update CMake test flags to define `ENABLE_TESTS` for `e1ap_lib`,
  and 5GS NAS libraries; drop `E1AP_LOG_ERRORS` - equality-check/error
  printing is now consistently controlled by `ENABLE_TESTS`

Guido Casati 9bfe62b85b RRC multi-cell (finalise): make internal helper functions static
After introduction of new cell management design, these helper functions
are now only used internally within their respective modules and do not
need to be part of the public API. They are made static and their
declarations are removed from public headers.

Changes:
- f1ap_interface_management.c: Make free_f1ap_cell() and
  copy_f1ap_served_cell_info() static
- f1ap_interface_management.h: Remove declarations for the above functions
- rrc_gNB_du.c: Make get_dl_band() and get_ssb_scs() static
- rrc_gNB_du.h: Remove declarations for get_dl_band() and get_ssb_scs()

Guido Casati 5d657c801c Refactor (F1AP): align cell lists definitions with TS 38.473
* 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.

Robert Schmidt 8f2e98a475 Upgrade F1AP to version 16.21.0
While implementing NRPPA-related F1AP messages, we remarked that
extension field "UL-AoA-ExtIEs" needs to be OPTIONAL (e.g., in NRPPA it
is optional in the OAI-compiled version), but it was not marked as such.
This later version 16.21.0 fixes this.

Robert Schmidt 3a4440a99c Generalize F1AP_LIB_FIND_IE() to work with list container
F1AP_LIB_FIND_IE() is used to look up elements in a list, but was
hitherto hardcoded to use "protocolIEs" as an intermediate struct. A
follow-up commit will use this macro where we don't have protocolIEs,
but "iE_Extensions". Hence, modify to make it work for that case (and
others) as well.

Robert Schmidt 2cc3f3bcac Fix: write NSSAI info of F1AP Cell Info struct
During refactoring, the previously implemented NSSAI field of the cell
info structure was not written to F1AP ASN.1 structures anymore;
eq_f1ap_cell_info() also conveniently omitted the corresponding equality
check. Add this back so the CU can correctly receive the NSSAI in case
of F1 split operation.

  Request (Interface Management) ")

Robert Schmidt ed876a53b2 F1: refactor out served_cell_info/du system info
Split out these functions, to be reused in a follow-up commit to
correctly have gNB-DU configuration update message working.

Change the return type copy_f1ap_served_cell_info(), to return the copy,
which IMO is more intuitive then passing target and source in
parentheses.
