sgsn: Add PDP info to subscriber data
Currently the PDP info that is transmitted via GSUP is just parsed
and then discarded.
This commit adds a new data structure sgsn_subscriber_pdp_data and
maintains a list of those in sgsn_subscriber_data. The PDP data is
copied from an incoming GSUP UpdateLocationResult message. If that
message contains the PDPInfoComplete flag, the list is cleared before
new entries are added. The 'show subscriber cache' output now also
shows the PDP data entries.
Note that the InsertSubscriberData message is still not supported.
