Change subject: drop features 'core-location-area-code' and 'core-cell-identity'
......................................................................
drop features 'core-location-area-code' and 'core-cell-identity'
This feature apparently assigned a fixed LAC and CI to a specific MSC, but
looking at the implementation was obviously not useful.
Keep the vty commands for legacy compat, now without effect besides logging an
error via vty_out().
