sgsn: Add a subscriber based authentication phase
This implements the MAP way of subscriber validation when the MS
tries to perform an Attach Request:
1. perform authentication (optionally invoke the sendAuthInfo
procedure), starts the Auth & Ciph procedure
2. perform update location
3. insert subscriber data
4. finish the update location
5. Attach Accept / Attach Reject
The authentication triplets are used and eventually updated if all of
them have been used.
This is currently accessible via the VTY interface by the following
commands:
- update-subscriber imsi IMSI update-auth-info
- update-subscriber imsi IMSI update-location-result (ok|ERR-CAUSE)
