sgsn: Integrate subscriber handling into the SGSN
This commit adds a new authorization policy 'remote' and uses
the subscriber cache for authorization when this policy is being used.
Note that there is no remote backend implemented yet. After the
IMSI/IMEI have been acquired, a request would be sent to the remote
peer. The attach/auth-ciph procedure continues when authorization
info has been received from the peer. This means, that
gprs_subscr_update() must be called then to tell the GMM layer
that it can proceed. A later commit will add VTY commands to do this
manually.
