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)
