The omit force this field to be not present, while a * allows to be present or not.
As user of this tr I would expect to ignore this field rather than an explicit omit.

This is an early WIP, we actually will need to establish two calls/legs

Recently we introduced a few new GSUP IEs, related to TCAP-like
session management and Supplementary Services in libosmocore.
Let's sync the TTCN-3 implementation and add the corresponding
templates for SS payloads.

We will soon implement some LCLS related test cases, and hence
we need some templates for sending and matching received messages.

procedure ports (like message ports) require us to specify the
destination of a message ("reply") in case it is connected 1:N and not
just 1:1. This didn't show up as a problem so far, as we typically only
had one component talking to those procedure ports at any given point
in time.

In I483ddd45c1cf631a5a9d8f862b6ca728b38bdc14 we introduced code
that makes the IPA_Emulation code to emut an ASP_IPA_EVENT_ID_ACK
[also] to the RSL port, irrespective of client/server status.
However, RSL_Emulation only handled this event in the BTS role
for BSC testing, but not in in the BSC role for BTS testing.

In non-handler mode, the SCCP emulation is currently started before
there's a user registered to SCCP_SP_PORT. If the first BSSMAP
package arrives from the network, then the SCCP_Emulation will crash
as it cannot deliver the resulting SCCP user primitive to the user.
Let's split start from initialization, so user code can still register
something to SCCP_SP_PORT before starting SCCP_Emulation.

osmo-pcu discards PAGING-PS messages unless received on the
signalling BVCI 0. The BVCI value must be set to zero both
in the NS header and the BSSGP header. Create new ports between
the PCU_Test components which the TC_paging test case can use
to ensure that both layers send frames with BVCI value of zero.
This does not make PCU_Tests.tc_paging work yet, however the PS
paging request is now processed by osmo-pcu rather than discarded.

Before this patch, we had some problems related to synchronization
between the IPA transport, SCCP emulation and BSSAP layer in SCCPlite
configurations.
This code ensures that f_bssap_init() will block until the IPA
connection (client or server) is established, and then start the SCCP
and BSSAP emulation components in the right order.
This in turn ensures that the initial BSSMAP RESET that we're sending
from the TTCN-3 side is only sent once the IPA connection is fully
established, and the CCM Identity handshake has happened before.

When sockets cannot be bound or connected, the existing TTCN-3 code prints
the following rather cryptic error messages:
"IPA-CTRL-IPA(47)@f70ff1fd5cfd: Dynamic test case error: Using the value of an optional field containing omit. (Transport endpoint is not connected)"
The "Transport endpoint is not connected" sort-of gives it away, but
let's make it more explicit by introducing explicit checks for the
res.connId and manual setverdict(fail) statements with proper error
message.

For some reason, the "FIELDORDER(lsb)" only worked for U-frames,
but not for S- and I-frames. Probably a TITAN bug, but rather than
debugging that now, let's rewrite the LAPDm types as "FIELDORDER(msb)"
as that appears to work.

Add ability to test UMTS AKA, by f_gmm_attach() with flags to select UMTS AKA
and to respond to it with GSM AKA SRES.
Add TC_attach_umts_aka_umts_res and TC_attach_umts_aka_gsm_sres.
Change existing TC_attach_* to also call f_gmm_attach(). (Actually,
f_gmm_attach() is almost exactly the previous TC_attach function body.)
osmo-sgsn change I36807bad3bc55c0030d4f09cb2c369714f24bec7 will implement
proper handling of GSM AKA response and make TC_attach_umts_aka_gsm_sres pass.

Our TTCN3 implementation of the IPA multiplex with CCM handshaking
has been based on some wrong assumptions about the protocol logic.
To make the code stricter, we
* send an ID_ACK immediately after connecting TCP in a client
* separate client and server CCM responder logic
* always respond with ID_ACK to ID_RESP (we accept any identity)
Also, as the Osmocom CTRL interface uses an IPA multiplex but no CCM,
we introduce a boolean variable (and function argument) to clearly
enable/disable CCM support in a given IPA_Emulation component. The
CTRL_Adapter has been modified to use this flag to disable CCM.
This also removes the need of cherry-picking

Add VTY functionality to GGSN tests, and use the VTY to enable/disable
GTP-U Tx sequence numbers in the running osmo-ggsn.
The GTPU packet template now makes sequence numbers optional.
A template created with its sequence number set to 'omit' will result in
a packet without a sequence number, i.e. the 'sequence number present' bit
in the packet header is cleared, and the sequence number field is omitted
from the encoded GTPU T-PDU packet.
Re-use the existing TC_pdp4_clients_interact() test for testing the
behaviour of osmo-ggsn. This test is now run twice, once with and
once without GTP-U Tx sequence numbers. Verify that packets relayed by
osmo-ggsn match its "g-pdu tx-sequence-numbers" configuration setting.

The MDISC_IPACCESS is only used for the media (CRCX/MDCX/DLCX) related
commands, not for the PDCH activation/deactivation. The latter uses
normal MDISC_DCHAN.
Also, add the inverse templates for PDCH actiation/deactivation, so we
now have both receive and transmit template for each of the 6 related
messages (activation, deactivation, plus each their ACK + NACK).
