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.

Since the logging allocations now also show up in the root context report, some
tests need adjusted talloc checks.
In msc_vlr_tests, also output the number of talloc blocks before tests are
started to show that the number didn't change after the tests.

The naming of "bump" was short and made sense to me at the time of writing, but
it is keeping pretty much everyone else at a distance, no-one intuitively gets
what it is supposed to mean.
Clarify by renaming to "release_when_unused".
Adjust test expectations.

Also indicate in msc_vlr_test_gsm_authen.c that we're indeed sending no

Three recently merged commits take the msc_vlr_tests in a wrong direction.
The IMSI is usually encoded in the hex streams. The rationale behind hex
streams is that it is a) easily copied from a wireshark trace and b) exactly
the bytes as sent by an actual phone. It is hard to parameterize the IMSI
because we would have to employ our encoding functions, which I intentionally
want to keep out of the loop here.
The test number should not appear in the normal test output, so that adding a
test or changing their order does not affect expected output for following
tests. The nr is simply for manual invocation, only seen when invoked with -v.

This is another left-over VTY command from the OsmoNITB days.
If such functionality is desired, it must be implemented in OsmoHLR,
but not here.

For each test print:
* the test number
* IMSI
Unfortunately tests are organized in such a way that we don't know the
number of particular test in advance. Nevertheless, it make sense to
always print it regardless of -v option presense.

It's not clear cut which code is responsible for canceling pending requests,
since the requests list is kept in vlr_subscr, but sending out Paging does
certainly not belong in the VLR. Place the requests cleanup in gsm_04_08.c.
Add to test_ms_timeout_paging() in msc_vlr_test_ms_timeout.c to verify that a
pending paging is canceled on IMSI Detach.

Currently, if there is no reply from the BSS / RNC, a subscriber will remain as
"already paged" forever, and is never going to be paged again. Even on IMSI
Detach, the pending request will keep a ref count on the vlr_subscr.
Add a paging timeout, as gsm_network->paging_timeout and in the VTY on the
'msc' node as 'paging timeout (default|<1-65535>'. (There is a 'network' /
'T3113' in OsmoBSC, but to not confuse the two, give this a different name.)
Add test_ms_timeout_paging() test to verify the timeout works.
I hit this while testing Paging across multiple hNodeB, when a UE lost
connection to the hNodeB. I noticed that no matter how long I wait, no Paging
is sent out anymore, and found this embarrassing issue. Good grief...

When hunting a conn use count bug, it was very hard to figure out who's (not)
using the conn. To ease tracking down this bug and future bugs, explicitly name
what a conn is being reserved for, and track in a bit mask.
Show in the DREF logs what uses and un-uses a conn. See the test expectation
updates, which nicely show how that clarifies the state of the conn in the
logs.
On errors, log them, but don't fail hard: if one conn use/un-use fails, we
don't want to crash the entire MSC before we have to.

Terminating one of the FSM instances may effect termination and deallocation of
the others, as well as the vlr_subscr itself. So, reserve the vlr_subscr
locally, and then dispatch events to exactly those FSM instances that exist.
The changes in expected output in the msc_vlr_tests shows that the subscriber
was deallocated from the first FSM termination, and now sticks around until
we've checked both FSMs are gone.
Change-Id: I56551ecc10f5295fe75944bdde4b583b1b621811
If dispatching a conn timeout, the conn fsm will already have been discarded,
and we cannot fire any more events to it.
The expected test output changes illustrate that we are now omitting event
dispatches that happen *after* the same FSM was already deallocated.

This was originally a long series of commits converging to the final result
seen in this patch. It does not make much sense to review the smaller steps'
trial and error, we need to review this entire change as a whole.
Implement AoIP in osmo-msc and osmo-bsc.
Change over to the new libosmo-sigtran API with support for proper
SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and
IuPS interfaces.
From here on, a separate osmo-stp process is required for SCCP routing between
OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN
jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new
M3UA SIGTRAN.

On incoming 04.08 messages, we log only the protocol discriminator in
decimal. Enhance: log pdisc and message type in hex, and also log the
protocol and message type as human readable string.
Also adjust the msc_vlr tests' log statements for wrapped rx/tx functions
of dtap from/to the MS.
Adjust the expected output of msc_vlr_tests.
