When a CSFB call is over the MS changes back to LTE after the call is
cleared. However, at the moment the MSC does not change the
cs.attached_via_ran flag. This may cause problems with the next call. Lets
make sure that if there is an SGs association present, the ran type is
set back to SGs when the call is cleared.

When the VLR/MSC receives an SGsAP-MO-CSFB-INDICATION message it sets
the RAN type back to SGs. This is wrong, the message
SGsAP-MO-CSFB-INDICATION has just an informative character. It informs
the VLR that the UE has initiated an MO CSFB call (service request).

Recently, the ability to run UTRAN without encryption was added, but the config
for it was tied to the A5 GERAN encryption configuration. This affected
osmo-msc's default behavior of Iu, breaking osmo-msc ttcn3 Iu tests: the ttcn3
test suite sets A5 to 0 (no encryption) but still expects Iu to enable air
encryption. Fix this "regression".
Add a separate vty config option for UEA encryption, even if it does not
provide full granularity to select individual UEA algorithms yet.
As a result, Iu default behavior remains to enable encryption regardless of the
A5 config. UTRAN encryption can be disabled by the new cfg option
"encryption uea 0" alone.
Even though the new vty command already allows passing various combinations of
the UEA algorithm numbers, only '0' and '1 2' are accepted as valid
combinations, to reflect current osmo-msc capabilities.
Revert most changes to the msc_vlr test suite in commit "do not force
encryption on UTRAN" (I04ecd7a3b1cc603b2e3feb630e8c7c93fc36ccd7): use new
net->iu_encryption instead of net->a5_encryption_mask.
Adjust/add to test_nodes.vty transcript tests.

Event VLR_ULA_E_ID_IMEISV is listed as permitted in VLR_ULA_S_WAIT_LU_COMPL,
but is missing from the switch() on the incoming event. So, sending an IMEISV
identity during the WAIT_LU_COMPL state would crash osmo-msc.
When receiving an IMEISV, vlr_subscr_set_imeisv() in turn calls
vlr_subscr_set_imei(), so as far as the lu_fsm is concerned, receiving an
IMEISV is identical to receiving an IMEI, and it can continue to send a Check
IMEI request to the HLR. Thus simply add VLR_ULA_E_ID_IMEISV to the
VLR_ULA_E_ID_IMEI switch case.

Following I04ecd7a3b1cc603b2e3feb630e8c7c93fc36ccd7, have tests for UMTS
authentication both for cases with and without encryption.
- Rename test_umts_authen_utran to test_umts_auth_ciph_utran() (uses
encryption).
- Again add test_umts_authen_utran() not using encryption.
- Likewise with test_umts_authen_resync_utran().
Some permutations are still missing, like UMTS AKA on GERAN with encryption
enabled; not bothering at the moment.

Remove the conditions that always enable encryption on UTRAN.
We so far lack an explicit configuration for UTRAN encryption, and this patch
does not add any either. Instead, whether UTRAN encryption is enabled is simply
triggered on whether GERAN has A5 encryption enabled (A5/n with n > 0). Though
GERAN and UTRAN encryption are not technically related at all, this makes UTRAN
behave like GERAN for now, until we implement a proper separate configuration
for UTRAN encryption.
Adjust the msc_vlr_test_* configuration by setting the net->a5_encryption_mask
such that the expected output remains unchanged. A subsequent patch
(I54227f1f08c38c0bf69b9c48924669c4829b04b9) will add more tests, particularly
cases of UTRAN without encryption.
Adjust manual and vty doc.

Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its
parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However,
definition in C file doesn't contain "(void)", which means number of
parameters is undefined and thus compiler doesn't complain. Let's remove
parameters from all callers before enforcing "(void)" on it.

Don't call tx_lu_rej() in the "vlr_lu_compl" FSM. It is always getting
called in the parent "lu" FSM and is therefore redundant:
_vlr_lu_compl_fsm_done(fi, VLR_FSM_RESULT_FAILURE, cause)
-> osmo_fsm_inst_state_chg(fi, LU_COMPL_VLR_S_DONE, 0, 0)

The RANAP DirectTransfer message may contain an optional SAPI IE.
Thanks to our TTCN-3 tests (and Wireshark!), it was discovered
that this IE is ignored, so even if the MO SMS related messages
arrive on SAPI 3 (as per GSM TS 04.11, section 2.3) OsmoMSC sends
MT messages on SAPI 0.
In ran_iu_decode_l3() we need to check if the SAPI IE is present,
and tag the NAS PDU message buffer with a proper DLCI value.
This change makes the failing SMS related test cases pass.

When periodic Location Update is disabled (T3212 = 0), it was noticed
that OsmoMSC does expire subscribers quite soon - after 60 seconds
(VLR_SUBSCRIBER_LU_EXPIRATION_INTERVAL) since the last LU.
In order to avoid that, we need to check T3212 timer value in
vlr_subscr_expire_lu(), and if it's equal to 0, do not expire
anybody until the explicit IMSI Detach.

This message can be used by the HLR/EUSE to indicate that something
went wrong, e.g. the connection with EUSE is lost, EUSE or the MS
did not respond in time, etc. OsmoMSC needs to release the SS/USSD
transaction, and send GSM 04.80 RELEASE COMPLETE message to the MS
if there is an active RAN connection.

This check was copy-pasted either from CC, or from SMS handling
code during the initial development of "SS/USSD over GSUP". Now
this is the only one survived after the recent refactoring.
I doubt this is exactly the right way to check whether subscriber
is attached or not. Moreover, this check should rather be done in
a single place, rather then in each CC/SS/SMS handler separately.

In case of network-originated SS/USSD session establishment, we
need to verify the received GSUP PROC_SS_REQ message and make
sure that all mandatory IEs are present.
There is no sensible need to allocate a new transaction before
doing all the checks, other than the ability to use LOG_TRANS().
This complicates the code, so let's avoid the early allocation.
