Add integration tests for RRC cell and DU management and UE serving-cell
logic so that multi-cell behaviour and regressions can be validated
without running the full stack.
* test_du_lookup() – DU container lookup by assoc_id:
- Multiple DU creation and insertion into RRC DU tree
- Lookup of existing DUs by assoc_id
- Non-existing and invalid assoc_ids
- Cleanup of DU containers and cells
* test_cell_lookup() – Cell management and UE association:
- Cell lookup by cell_id and PCI (global and per-DU)
- DU-specific lookup: rrc_get_cell_for_du(), rrc_get_cell_by_pci_for_du()
- Duplicate cell and PCI collision handling (including PCI reuse across
DUs and rejection of duplicate PCI within same DU)
- Cell–DU association (add/remove cells from DU containers)
- UE serving cell: add PCell/SCells, get by ID, get PCell, max serving
cells limit, single PCell enforcement
- validate_ue_cell_association(), rrc_remove_ue_scells_from_du()
- Edge cases and error handling
Add openair2/RRC/NR/tests/rrc_cell_management_test.c and extend
openair2/RRC/NR/tests/CMakeLists.txt to build and register the test.
