bsc: Allow to have a list of MSCs/MUXs to connect to
Be able to configure a list of destinations (duplicates allowed) that will be tried in a round robin fashion. The change is in the bsc_msc_connection to operate on a list. We achieve the round robin nature with the same trick used in the paging code to delete and append the current entry. The nat code was updated to compile but one can only configure one destination.
