open5gs-smfd is since recently acting properly and setting the proper
TEIC when sending GTPv2C messages for cases where session is not found.

open5gs-smfd was recently modified to send RAT-Type inside
PS-Information instead of MSCC, since having it in the former is
supported since older spec releases and having it in the later creates
problems in some real world OCS implementation like PortaOne OCS.

The fields were added to be used in EPDG_Tests, but they need to be

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.

This test allows initial testing of a session creation through the S2b
interface (emulating an ePDG).
A follow-up test will be added to test the APCO IE (feature which
open5gs-smfd still doesn't support).

So far we were only testing s5/s8 interface, but we'll want to test s2b
soon.
This commit is a mixture of refactorings and code improvements as a step
towards testing S2b interface.

Those interfaces reuse messages from other Diameter RFCs, but changing
the contents of the messages, eg some Mandatory fields like
Service-Context-Id which are mandatory in RFC5006, doesn't even appear
in Gx CCR in TS 29.212.
Keeping them well separated helps in avoiding confusion on users fo the
messages.

A recent commit in GTPv2_Emulation improved the routing of incoming
messages from network towards clients.
After that change, the GTPv2_Emulation properly matches the originating
component of the procedure and forwards the reply to it.
Hence, TC_tx_echo() needs to be adapter to expect the reply on its
CLIENT port.
TEID0 is now left for incoming initiating messages which have no seqnr
match.

open5gs 125740727e558c7604897eda711d4d40f2906239 changed behavior and is
no longer sending the Used-Service-Unit AVP during INITIAL_REQUEST,
which makes sense since those values should be only initialized and
spec seems to more or less expect it that way, though receiving it at
INITIAL time should be accepted too AFAICT.

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.

Multiple-Services-Indicator AVP is only meant to be sent in CCR Init.
Let's not expect it in Update nor in Termination CCR, open5gs stopped
sending it there recently in 9948fba05afb8e1b118f0c29a84ffe38c0f21b75.

All the AVP ecosystem in DIAMETER is quite a mess. There's AVPs defined
in several different specs, sometimes even with the same name and
different AVP code and vendor.
Hence, as we add more templates it becomes important to start using the
prefix in order to differentiate where they come from.

The Reporting-Reason can be in different places depending on its values.
In the case of TERMINATION, we expect it to be FINAL so we know its

A new intermediate component DIAMETER_ConnHdlr_CT is added which extends
the required DIAMETER_ConnHdlr by the DIAMETER_Emulation, and forwards
it to the PGW_Session_CT. This way, the PGW_Session_CT, which usually
runs the test code, will have access to GTP2, Gx and Gy messages for the
session.
Initial Gy support for PGW_Tests is added in follow-up patch.

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.
