The Types are already split in the dependent modules in GTPC_Types and
GTPU_Types.
There's no point in keeping them together in the same file since those 2
protocols are mostly independent.
Furthermore, testsuites using GTPv2C + GTPv1U don't need GTPv1C.

NAS Token is derived from kasme and NAS ul_count as specified in 3GPP TS
33.401 A.9, and its LSB 16 bits passed to the network when mapping the GUTI to
RAI+PTMSI+PTIMSI_SIG.
Take the chance to move guti2rai_ptmsi() up to before the place it is
used.

The previous logic was wrong, since it was increasing the rx_count at
the time where the msg is received and before checking it. Instead, it
should be increased after having validated and accepted it.
This fixes the case where rx_count will have to be reset (to zero) when
doing mobility GERAN->EUTRAN.

The MME is sending the message after TAU Reject, and it may be forwarded

According to 3GPP TS 23.003 sec 2.8.2.2.2, LACs from GERAN are
configured with MSB 0 in order to differentiate it from EUTRAN ones.
This is used by MMEs to figure out if the peer is an SGSN, based on
the the LAC mapped into MME group ID in GUTI .

This will be used further in subsequent tests, plus it is configured in

Some later parts of the 4G->2G cell reselection where missing, mostly
related to tear down after MS has successfuly moved to the new SGSN. mainly:
- S6a Diameter Cancel Location Req + Answer initiated by HSS.

UeReleaseContextComplete, emulating the ENB.
- handle S11 GTPv2C Delete Session Request and answer with Delete
Session Response, emulating the SGW.

Before this patch, the rx_count field was never set to anything other
than zero.
There's still a problem with counter not being incremented when a
S1AP_IntialCtxSetupReq message containing a NAS_PDU is received. This
will be fixed ina follow-up patch.

The testcase TC_s1ap_attach is not complete yet. Since the testsuite
lacked the S11 interface, it was not possible to develop the testcase
beond the S1AP/NAS-EPS Security Mode Command. However, the S11 interface
is now available to the testsuite, so let's show that it works by
catching the Create Session Request. Let's also put a TODO that the
testcase needs to be completed still.

The S11 interface is used by the MME to talk to the SGW-C. At the moment
we do not simulate the S11 interface in our testcases. This is in particular
a problem for TC_s1ap_attach, which needs to answer the Create Session
Request, comming from the MME in order to continue.
As a first step, lets add evrything that is required to run an S11
interface in the testsuite.

This is useful in the scenarios where the client component submits a
IMSI-based transaction such as AIR, but its answer (AIA) contains no
IMSI (as per what's specified in TS 29.272 5.2.3.1). As a result, the
received AIA message would be enqueued in the DIAMETER_UNIT.
With this new feature, the test can create an expect using the
End-to-End Identifier of the message it is going to transmit, and
receive the answer in the same DIAMETER_CLIENT port the request was
transmitted, even if it contains no IMSI.

The proposed testcase models a full RIM RAN INFORMATION REQUEST that
originates at the eNB (S1AP), is forwarded by the MME towards GERAN
(GTP) and goes back towards the MME (GTP) and is eventually forwarded
by the MME back to the eNB (S1AP).

To test the planned Gn connectivity support in open5gs MME the testsuite
also requires support for such an interface. This patch adds the
connection handler, provided by GTP_Emulation.ttcn to the connection
handler in MME_Tests.ttcn, along with a simple GTP ECHO REQUEST
testcase.

At the moment we do not have a default implementation for the create_cb.
The create_cb is called to resolve the vc_conn to which a subscriber
communication belongs in case it is not found in the S1apAssociationTable,
then it is resolved from an S1apExpectTable instead.
The current implementation uses the IMSI as key to resolve the vc_conn
from the S1apExpectTable, this might not work since in S1AP the UE
context is identfied by an MME_UE_S1AP_ID / ENB_UE_S1AP_ID pair.

The new message is to be used by Gy interface emulation, which according
to RFC4006 uses AppId 4 "Credit Control Application". The application
is apparently not 3GPP vendor specific.

This patch implements a new mode of operation, which allows to
have direct communication between the emulation component and
the other component connected via the 'DIAMETER_UNIT' port.
This eliminates the need to have dedicated components for each
IMSI, what is not necessarily needed in some specific cases.
