bsc: Implement paging by creating a dummy subscr for the paging
In the future we should avoid using a gsm_subscriber at all
and pass the imsi/tmsi to the paging function directly. For
now we can use the old model for paging and go through the
gsm_subscriber. This has the benefit of load balancing on
the BTS and such.
