add 'show bts N neighbor-si', test SI ARFCNsneels/legacy_neighbors

How the new way of indicating neighbor cells interacts with the various System
Information coding and manual SI modes is yet badly under-tested.

- Add vty command 'show bts N neighbor-si' to generate the frequency lists as
  would be sent out via OML in the System Information IEs.

- Add neighbor_si.vty VTY transcript test to verify the various neighbor
  configurations and what SI frequency lists they produce.
