gsm0808: add BSSMAP Cell Identifier matching API
Add * osmo_lai_cmp() (to use in gsm0808_cell_id_u_matches()) * osmo_cgi_cmp() (to use in gsm0808_cell_id_u_matches()) * gsm0808_cell_id_u_match() (to re-use for single IDs and lists) * gsm0808_cell_ids_match() * gsm0808_cell_id_matches_list() * Unit tests in gsm0808_test.c Rationale: For inter-BSC handover, it is interesting to find matches between *differing* Cell Identity kinds. For example, if a cell as CGI 23-42-3-5, and a HO for LAC-CI 3-5 should be handled, we need to see the match. This is most interesting for osmo-msc, i.e. to direct the BSSMAP Handover Request towards the correct BSC or MSC. It is also interesting for osmo-bsc's VTY interface, to be able to manage cells' neighbors and to trigger manual handovers by various Cell Identity handles, as the user would expect them.
