SGSN VTY: make missing GSUP server address+port fatal
On 'auth-policy remote', the SGSN requires GSUP server address and port. If
it
was missing, the SGSN would print a VTY warning and run anyway. Make this error
more fatal: print an error (flattened a bit) to stderr and abort the program.
Move validation of the GSUP server data presence out of the VTY command itself
and into the config reading function. This way the GSUP server config can be
given anywhere, including below the auth-policy config (was required above).
Don't care about setting the auth-policy to remote with a telnet VTY, because
in that case the GSUP client won't be started anyway.

SGSN: Integrate support for UMTS AKA
The general infrastructure for UMTS AKA is already in place:
* GSUP with capability to send us auth_vectors that contain
either triplets or quintuples
* mm_context that holds such auth_vectors
Add:
* capability to send UMTS AUTN in GMM AUTH REQ
* parse extended UMTS RES
* on auth response, validate expected AKA with vector and received res/sres
* add Auth Failure message to receive resync AUTS token and
* send to HLR
* clear out-of-sync auth tuple
* enter new state for when we're waiting for HLR to resync and send new
tuples so that the next Auth Request will be handled
Original first half of this patch by: Harald Welte <laforge(a)gnumonks.org>
Full UMTS AKA procedure including AUTS resync tested to work against OsmoHLR
with R99 USIM and Milenage algorithm.
The sgsn_test.c needs adjustment because we're checking the vector's
auth_types
now.
