Store all Classmark information in the VLR.
So, we now always know the Classmark 1 (mandatory IE for LU). This is visible
in the msc_vlr_tests -- they no longer indicate "assuming A5/1 is supported"
because classmark 1 is missing, because we now know the Classmark 1.
Rationale:
During Location Updating, we receive Classmark 1; during CM Service Request and
Paging Response, we receive Classmark 2. So far we stored these only for the
duration of the conn, so as soon as a LU is complete, we would forget CM1.
In other words, for anything else than a LU Request, we had no Classmark 1
available at all.
During Ciphering Mode Command, we rely on Classmark 1 to determine whether A5/1
is supported. That is moot if we don't even have a Classmark 1 for any CM
Service Request or Paging Response initiated connections.
The only reason that A5/1 worked is that we assume A5/1 to work if Classmark 1
is missing. To add to the confusion, if a phone indicated that it did *not*
support A5/1 in the Classmark 1, according to spec we're supposed to not
service it at all. A code comment however says that we instead want to heed the
flag -- which so far was only present in a Location Updating initiated
connection. Now we can make this decision without assuming things.
This got my attention while hacking on sending a BSSMAP Classmark Request from
the MSC if it finds missing Classmark information, and was surprised to see it
it lacking CM1 to decide about A5/1.

The intention was to use the file's basename, but __BASE_FILE__ means "the root
file that is being parsed and contains #include statements".
If we had a function using __BASE_FILE__ and that was defined in an #included
file, __BASE_FILE__ would indicate the first file where the #include is, and
not the file where the function is defined. __BASE_FILE__ works for us because
we don't ever include function definitions that log something, so __BASE_FILE__
always coincides with __FILE__ for our logging; but still __BASE_FILE__ is
semantically the wrong constant.

When the assignment completes a choosen codec is returned. At the
moment we do not use this information.
- add struct members for codec info (both, RAN and CN)
- parse codec info in BSSMAP ASSIGNMENT COMPLETE
- use codec info on mgcp
Since the MNCC API is not complete yet, we currently only use the
codec info only on the internal MNCC yet.

osmo-hlr has recently (as of Change-Id
Iad227bb477d64da30dd6bfbbe1bd0c0a55be9474) a working shared library
implementation of libosmo-gsup-client.
We can remove the local implementation in osmo-msc and use the

Since we don't process SS/USSD requests in OsmoMSC anymore, there
are some useless GSM 04.80 functions remained from the past.
In particular, this change does the following:
- removes both gsm0480_send_{ussd_response|return_error}
functions because they are not used anymore;
- changes symbol prefix from 'gsm0480_' to 'msc_', in order to
avoid possible conflicts with the libosmogsm's GSM 04.80 API;
- cleans up useless includes;

This change introduces some new rate counters for call-independent
SS/USSD connections. As OsmoMSC doesn't handle the messages itself,
and only responsible for dispatching messages between both
A and GSUP interfaces, the following is taken into account:
- MS-initiated and network-initiated requests to establish
a NC SS/USSD session (transaction) - "nc_ss:m{o|t}_requests";
- successfully established MS-initiated and network-initiated
SS/USSD sessions (transactions) - "nc_ss:m{o|t}_established".

This change introduces a possibility to establish network-initiated
SS/USSD transactions with a subscriber in either IDLE, or DEDICATED
state. In the first case, a new transaction is established using
Paging procedure. If a subscriber already has an active connection,
a separate new transaction is established.

In order to be able to support external SS/USSD gateway, we should
not terminate the GSM 04.80 messages at OsmoMSC. Instead, we need
to follow the GSM TS 09.11 specification, and forward all messages
unhandled by OsmoMSC to OsmoHLR over GSUP protocol.
This change implements forwarding of MO SS/USSD messages. The
forwarding assumes transcoding between GSM 04.80 messages and
GSUP messages. The payload of Facility IE is carried 'as is'.
As a side-effect, this will disable the osmo-msc internal handler
implementing the "*#100#" for obtaining the subscribers own phone
number. In order to re-gain this functionality, you will need a
modern osmo-hlr (Change-Id I1d09fab810a6bb9ab02904de72dbc9e8a414f9f9)
and the following line in your osmo-hlr.cfg:

Some internal sub-systems, such as SS/USSD or SMS implementation,
may also need to use GSUP connection with HLR. Previously, it was
only available within the libvlr code, and nowhere else.
Let's introduce the generic GSUP message router, which will
receive messages unhandled by VLR itself, and route them to
a handler depending on the message type.

The CC sub-layer is fairly self-contained, so let's move it to
a separate C source file. The old gsm_04_08.c file now only
contains the 04.07 / DTAP core and MM sub-layer handling.
I did this initially as an experiment to see how self-contained
our CC implementation really is. Given this rather straight-forward
patch builds fine, CC really is self-contained (yay!).

There is no need to pass a pointer to a ss_request struct when
calling the gsm0480_send_ussd_* functions, because they only
use both transaction ID and InvokeID from there, which may
be passed directly.
This change allows one to use this API without parsing the
whole GSM 04.80 message, or when parsing is failed. Moreover,
if InvokeID is not available, one can pass any incorrect,
(e.g. negative) value, so the universal NULL tag will be used.
Finally, setting a TI flag is also up to the caller.

During a long time, we had both file and symbol names, actually
related to Supplementary Services, with the 'ussd' abbreviation.
This is not absolutely wrong, but isn't correct at the same time.
USSD is a kind of Supplementary Services, this is only a part
of them. There are also 'structured' Supplementary Services,
which can be call related or call independent.
The "Signalling interworking for supplementary services" is
defined by GSM TS 09.11, and this is exactly what MSC should
implement. Let's use the specification number for naming, as
we do e.g. in the GSM 04.11 (SMS) implementation.

There are error and problem codes defined by GSM TS 04.80:
- Error codes are used when a message is structured correctly,
but something is wrong in context of the current operation.
Usually they are carried by 'Return Error' component.
- Problem codes are used when something is wrong with the
message structure, or with carried values. They are
carried by 'Reject' component.
There are three groups of them (see table 3.13):
- General Problem Codes (table 3.14),
- Invoke Problem Codes (table 3.15),
- Return Result Problem Codes (table 3.16),
- Return Error Problem Codes (table 3.17).
The first group is general purpose, and can be sent in
response to any kind of message, excluding 'Reject' itself.
Other ones are bound to specific component types, such as
'Invoke', 'Return Result' and 'Return Error'.
For some reason, a 'Reject' component with the general problem
code 'GSM_0480_GEN_PROB_CODE_UNRECOGNISED' was always used in
OsmoMSC. Even when the message structure is correct.
Let's properly indicate errors in the following way:
- 'Reject' with GSM_0480_GEN_PROB_CODE_UNRECOGNISED
when the gsm0480_decode_ss_request() fails to decode
a message. It can only return 0 or 1, so it's hard to
guess which exact part of message caused the error.
- 'Return Error' with GSM0480_ERR_CODE_ILLEGAL_SS_OPERATION
when the operation code is not related to USSD.
- 'Return Error' with GSM0480_ERR_CODE_UNEXPECTED_DATA_VALUE
when the requested USSD code is unhandled (not supported).
There is a TTCN-3 testcase for this:

Remove subscribers which fail to send periodic Location Updates from the
list of subscribers known to the VLR. This complements the IMSI detach
procedure: periodic LU expiry triggers an implicit IMSI detach.
Expired subscribers are purged from a periodic timer which iterates
over all subscribers once per minute.
Subscribers with an active connection do not expire. This is controlled
by the subscriber conn FSM which sets a subscriber's the LU expiry timeout
value to GSM_SUBSCRIBER_NO_EXPIRATION while a connection is active.
Add support for fake time with osmo_clock_gettime() to msc_vlr tests.
This functionality existed in OpenBSC but was lost during the nitb split.
This code took some inspiration from the OpenBSC implementation.

a_reset.c/h was originally developed to be used in both, bsc and
msc without changes. Unfortunately no suitable library has been
found for a_reset.c/h so the file ended up as duplicated code in
both split brances. Eventually we decided to specialize the
generalized code again, which means some of the functions needed
only by osmo-bsc are removed.
- Remove dead code
- Fix timer identification number (T16)
- use fi->priv to hold context info
- Minor cosmetic fixes

The only reason to use int instead of the enum was the lack of header
iu_client.h when not building with Iu support. Rather use the configure result
properly, include the header when Iu support is built and use the proper enum.
Omit the entire iu sub-struct when building without Iu.
Add LIBOSMORANAP_CFLAGS to libvlr, in order to find the iu_client.h header (now
also included from gsm_data.h).
Rationale: Instead of using a questionable typecast from int* to enum*, we can
now use the enum member directly without needing to silence compiler warnings.

Instead of keeping separate enums for FSM results and translating between those
and the actual 04.08 reject causes that will ultimately reach the MS, just pass
enum gsm48_reject_value cause codes around everywhere.
Collapse some VLR *_timeout() and *_cancel() api to just *_cancel() with a
gsm48 cause arg.
(Hopefully) improve a few reject causes, but otherwise just aim for more
transparent decisions on which cause value is used, for future fixes of
returned causes.

When sending a BSSMAP Clear or Iu Release, do not immediately discard the conn,
but wait until a BSSMAP Clear Complete / Iu Release Complete has been received.
Hence we will no longer show in the log that an incoming Release/Clear Complete
belongs to an unknown subscriber, but will still be around to properly log the
release.

Refactor:
1. Glue the gsm_subscriber_connection alloc to the subscr_conn_fsm.
2. Add separate AUTH_CIPH state to the FSM.
3. Use conn->use_count to trigger conn release.
4. Add separate RELEASING state to the FSM.
5. Add rate counters for each of the three Complete Layer 3 types.
Details:
1. Glue the gsm_subscriber_connection alloc to the subscr_conn_fsm.
Historically, a gsm_subscriber_connection was allocated in libbsc land, and
only upon Complete Layer 3 did libmsc add the fsm instance. After splitting
openbsc.git into a separate osmo-msc, this is no longer necessary, hence:
Closely tie gsm_subscriber_connection allocation to the subscr_conn_fsm
instance: talloc the conn as a child of the FSM instance, and discard the conn
as soon as the FSM terminates.
2. Add separate AUTH_CIPH state to the FSM.
Decoding the Complete Layer 3 message is distinctly separate from waiting for
the VLR FSMs to conclude. Use the NEW state as "we don't know if this is a
valid message yet", and the AUTH_CIPH state as "evaluating, don't release".
A profound effect of this: should we for any odd reason fail to leave the FSM's
NEW state, the conn will be released right at the end of msc_compl_l3(),
without needing to trigger release in each code path.
3. Use conn->use_count to trigger conn release.
Before, the FSM itself would hold a use count on the conn, and hence we would
need to ask it whether it is ready to release the conn yet by dispatching
events, to achieve a use_count decrement.
Instead, unite the FSM instance and conn, and do not hold a use count by the
FSM. Hence, trigger an FSM "UNUSED" event only when the use_count reaches zero.
As long as use counts are done correctly, the FSM will terminate correctly.
These exceptions:
- The new AUTH_CIPH state explicitly ignores UNUSED events, since we expect the
use count to reach zero while evaluating Authentication and Ciphering. (I
experimented with holding a use count by AUTH_CIPH onenter() and releasing by
onleave(), but the use count and thus the conn are released before the next
state can initiate transactions that would increment the use count again.
Same thing for the VLR FSMs holding a use count, they should be done before
we advance to the next state. The easiest is to simply expect zero use count
during the AUTH_CIPH state.)
- A CM Service Request means that even though the MSC would be through with all
it wants to do, we shall still wait for a request to follow from the MS.
Hence the FSM holds a use count on itself while a CM Service is pending.
- While waiting for a Release/Clear Complete, the FSM holds a use count on
itself.
4. Add separate RELEASING state to the FSM.
If we decide to release for other reasons than a use count reaching zero, we
still need to be able to wait for the msc_dtap() use count on the conn to
release.
(An upcoming patch will further use the RELEASING state to properly wait for
Clear Complete / Release Complete messages.)
5. Add rate counters for each of the three Complete Layer 3 types.
Besides LU, also count CM Service Request and Paging Response
acceptance/rejections. Without these counters, only very few of the auth+ciph
outcomes actually show in the counters.

The DLCI field of the DTAP header indicates the SAPI as well as the
data link (main DCCH or SACCH). We must make sure to use the correct
DLCI when sending DTAP to the BSC.
We achieve this by
* storing the DLCI in the msgb->cb while parsing the DTAP header
* storing the received DLCI (from msgb->cb) in the transaction for
mobile-originated transactions
* using the trans->dlci to sent msgb->cb when transmitting L3
* filling the DTAP DLCI value from msgb->cb when transmitting DTAP
For MSC-originated transactions, we choose a DLCI value corresponding
to the service (SAPI=0 for CC, SAPI=3 for SMS) and store that in
trans->dlci.

The current msc_subscr_con_allocate() was in fact only used by msc_vlr_tests,
while both a_iface_bssap.c and iucs.c did their own duplicate code of
allocating the gsm_subscriber_connection struct. Unify.
Drop the old msc_subscr_con_allocate(), instead add msc_subscr_conn_alloc().
The new function also takes via_ran and lac arguments directly.
The conn allocation will soon be closely tied to the subscr_conn_fsm instance
allocation, so place the new function definition alongside the other
subscr_conn_fsm API, and match its naming ("conn").

Instead of jumping through hoops to pass the Complete Layer 3 operation that
created this conn via FSM event dispatch parameters, put it right in the
gsm_subscriber_connection struct, where it always belonged.
Move definition of the enum complete_layer3_type to gsm_data.h, where
gsm_subscriber_connection is defined.
Introduce msc_subscr_conn_update_id() to set the complete_layer3_type of the
conn as soon as a Complete Layer 3 message is received.
In msc_subscr_conn_update_id(), already include an mi_string argument to
prepare for an upcoming patch where the FSM will be allocated much earlier when
the Mobile Identity is not known yet, and we'll also update the fi->id here.
The odd logging change in the msc_vlr_tests output uncovers a wrong use of the
osmo_fsm_inst_dispatch() data argument for SUBSCR_CONN_E_CN_CLOSE events: if a
child FSM signals unsuccessful result, instead of the failure cause, it passed
the complete_layer3_type, as requested upon FSM allocation, which was then
misinterpreted as a failure cause. Now a child FSM failure will pass NULL
instead, while other SUBSCR_CONN_E_CN_CLOSE events may still pass a valid cause
value.

No functional nor cosmetic changes have been made in the moved code, plain

In trans_free(), call subscr_conn_release_when_unused(), so that we are sure to
clean up after the last transaction is done.
This fixes an error where a conn lingered after a CC failure, because that code
path forgot to trigger cleanup.
Rationale: so far we were triggering the release check after each DTAP dispatch
(compl_l3 and "normal" DTAP), which is sufficient for properly closed
transactions. We also need a check for when a timeout clears an erratic trans.
Adjust test expectation of test_call_mo_to_unknown_timeout to show that the
error is now fixed.
msc_vlr_test_reject_concurrency now sees an additional release checking event
when the SMS transaction is done, which is expected and does not affect the
test otherwise.

gsm48_tx_mm_info() was not called anymore. No MM info messages were
transmitted to phones even if MM info messages were enabled via VTY.
With this commit, we call gsm48_tx_mm_info() after successfully
processing an IMSI ATTACH location update.

Define the struct vlr_ciph_result member .imeisv not as a char* but a char[] of
appropriate length, to avoid the need to point to external memory.
Thus fix a use-after-free in msc_cipher_mode_compl(), which defined the
imeisv[] buffer in a sub-scope within that function, so that the .imeisv
pointer was already invalid when fed to vlr_subscr_rx_ciph_res().
Did you notice that the commit summary rhymes?

Add 3-digit flags and use the new RAI and LAI API from libosmocore throughout
the code base to be able to handle an MNC < 100 that has three digits (leading
zeros).

All callers pass mcc=1, mnc=1, so just have it as default.
(Prepare for net->country_code etc to be replaced by net->plmn)

The ID will include the type of connection (GERAN_A, UTRAN_IU) followed
by the SCCP conn_id.
This can be used for the fsm instance ID before we know the IMSI.
