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.

bsc: The ip.access rtp-payload has no useful meaning
...
Sending this as the RTP_PAYLOAD2 will produce a MDCX NACK
as we send the RTP_PAYLOAD in the CRCX. It does not seem to
be necessary to send anything != 0 for the RTP_PAYLOAD2.
