This will prevent subsequent failures from overwriting the verdict so we
can easily see the root cause of the test failure.
Using testcase.stop instead for errors internal to our test
infrastructure to mark them as test errors instead of failed.

the TEID value. According to 3GPP TS 29.060 sec 9.3.1 in those cases the TEID is
set to 0:
"""

When the protocol configuration options (PCO) contain an IPCP container
then lists only one one DNS server (normally there are two included, a
primary and a secondary). Than the parser in osmo-ggsn runs into an
endles loop. This testcase tries to provoke this behavior by sending
PDP CONTEXT ACTIVATE messages with PCO that contain only a single DNS
entry per IPCP container.
The hanging of osmo-ggsn is already fixed (see Depends). However when
Primary and Secondary DNS are in separate IPCP containers, then only
the first IPCP container is parsed (see also OS#3381)

The test coverage of the RTP aspects of the MGW is currently very
minima. Lets add a few more testcase to verify RTP behaves as
expected in various situations.
- Add testcase TC_one_crcx_receive_only_rtp:
Test recvonly mode of the MGW. All packets must be absorbed by
the MGW, no packets must come back.
- Add testcase TC_one_crcx_loopback_rtp:
Test loopback mode of the MGW. All packet sent to the MGW must
come back.
- Add testcase TC_two_crcx_and_rtp_bidir:
We already test unidirectional transmissions. This test does
the same as TC_two_crcx_and_rtp but for both directions.
- Add testcase TC_two_crcx_mdcx_and_rtp:
Simulate a typical behaviour of a normal call. First create
two half open connections and complete the connections later
using MDCX.
- Add testcase TC_two_crcx_and_unsolicited_rtp:
Test what happens when a RTP packets from rogue source are mixed
into the RTP stream.
- Add testcase TC_two_crcx_and_one_mdcx_rtp_ho:
Test a typical handover situation. An existing connection is
handovered to another source on one end but the old source will
keep transmitting for a while.

The test currently use a hardcoded payload type and encoding name.
This does mean in practice that even when an assignment with EFR
is happeining. The MGCP responses to the BSC tell that the codec
is AMR. This is not correct. The testcases should always pick a
suitable payload type / encoding name in the MGCP response
- Add constants for IANA/3GPP assigned payload types
- Add function to lookup the right encoding name for a payload type
- Initalize the encoding name and payload type in g_media according
to the BSSAP PDU.

Until now, the test went from RR Handover Command directly to RR Handover

The existing test simply sent 1000 messages via RSL without checking
what actually arrived on the radio interface, or without

on Um vs. RSL DELETE IND arriving at BSC.

procedure ports (like message ports) require us to specify the

just 1:1. This didn't show up as a problem so far, as we typically only

in time.

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.

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
