The HLR must store the least-recently used VLR and SGSN identities in
its database to ensure subsequent mobile-terminated transactions can
be routed accordingly.
Change-Id: Ib2611421f3638eadc361787af801fffe9a34bd8a
Closes: OS#2796
There are some requests that are best served inside the HLR, as it
has access to subscriber information such as MSISDN and IMSI.
This unfortunately required quite some restructuring of the USSD
related structures including the VTY syntax for adding routes.
The default config file has been updated to replicate the *#100#
built-in behavior of old OsmoNITB.

This is a small program which simply echo's the USSD request message it
gets in a quote back to the sender. Its purpose is to illustrate how
EUSEs can be implemented using libosmo-gsup-client.

We don't want any SS session to run for more than 30s. The timeout

If we need more comprehensive timeout handling, using osmo_fsm for SS

Tracking NULL memory contexts allows one to detect memory chunks
allocated outside the application's root context, which in most
cases are the result of some mistake.
For example, the VTY implementation still uses the NULL context,
so we have to clean up it manually until this is fixed.
At the moment we have at least one chunk allocated outside the
application's root context (excluding the VTY context):
full talloc report on 'null_context' (total 24 bytes in 2 blocks)
struct lookup_helper contains 24 bytes in 1 blocks
Change-Id: I7ea86730e090c06b2a5966ae4d04b8144b1cd20a
This makes both ASAN and Valgrind happy, because they do expect
all allocated heap chunks to be released on exit.

During the attempt to fix OS#2785 in Change-Id
I6a92ca34cdaadca9eacc774bb1ca386c325ba865, we introduced logic that
would blindly insert a subscriber *concurrently* in all VLRs/SGSNs of
the network on any update of the subscriber.
Before that patch, we didn't update the current serving SGSN/VLR,
and after the change we created subscribers in all SGSNs/VLRs, of which
all-1 are not serving the subscriber at that time.
We'll have to go back to the original behavior until a proper fix can
be introduced.

Encode an Insert Subscr Data with is_ps == true to trigger the encoding bug
described in OS#3231, i.e. show that it is fixed.
Move osmo_gsup_addr_send() to a separate .c file, so that it can be overridden

This function relied on implementation details of the luop code.
Port what is necessary for an independent Insert Subscriber Data
Tx operation from the luop code into this function.
A next possible step would be to try to merge both of these
into a common implementation. This will be addressed in a
follow-up change as soon as this change is merged.
The TTCN3 test TC_vty_msisdn_isd is still passing (it currently
triggers the "circuit switched domain" case because it does not
advertise itself as an SGSN in the IPA unit name).

Add a function which triggers subscriber update notifications to
all connected GSUP clients, and invoke it when the MSISDN of a
subscriber is changed via VTY.
This makes the TTCN3 HLR test TC_vty_msisdn_isd pass.
Note that the new function currently relies on implementation
details of the Location Update Operation (luop) code.
Because of this we currently log a slightly misleading message
when the updated Insert Subscriber Data message is sent:
"luop.c:161 LU OP state change: LU RECEIVED -> ISD SENT"
This message is misleading because, in fact, no location update
message was received from a GSUP client at that moment.
So while this change fixes the externally visible behaviour, we may
want to follow this up with some refactoring to avoid relying on
luop internals. It seems acceptable to do that in a separate step
since such a change will be more involved and harder to review.
We may want to trigger such notifications in other situations as well.
This is left for future work, too. There are no TTCN3 test cases for
other situations yet, as far as I can see.

Use osmo_timer_setup() to set up the luop timer, instead of
settting the timer up manually.
Delete the timer before the luop is freed to prevent a potential
crash in case the timer is already armed and the function call
chain leading up to lu_op_free() does not cancel the timer.

If we have a subscriber entry that lacks auth data, we currently return
GMM_CAUSE_NET_FAIL, which in the MSC log looks like the HLR is not connected or
something grave. Instead, return GMM_CAUSE_IMSI_UNKNOWN.
This changes the OsmoMSC log in this way:
Before:
DVLR <001e> VLR_Authenticate(901700000014701)[0x5555558dabb0]{VLR_SUB_AS_NEEDS_AUTH_WAIT_AI}: GSUP: rx Auth Info Error cause: 17: Network failure
After:

A better cause value would be something that says "IMSI known, but we have no
auth data", but since such cause value is not defined, the plain "IMSI unknown"
seems to be the best match.
