Fixes for E1 and PDU session usage
Fix a number of problems in E1 and PDU session handling:
- For multiple PDU session setup reqs, we send a bearer context setup
each time; fix an assert that was triggered on the second bearer
context setup message
- Add a log for E1 bearer context setup, as already done for
modification and release
- If we get a PDU session setup for an existing PDU session, reject it
as required by the spec [actually, it says to reject individual PDU
sessions; keep it simple for now and reject the entire message, which
might not be correct if there is one new PDU session that does not
exist]
- Add a workaround to handle multiple PDU session setup requests that
come in quick succession for different PDU sessions
Leading to clang error:
/oai-ran/openair2/RRC/NR/rrc_gNB_NGAP.c:1329:37: error: result of comparison of constant 256 with expression of type
'uint8_t' (aka 'unsigned char') is always false [-Werror,-Wtautological-constant-out-of-range-compare]
The value comes from the decoding of: ie->value.choice.PDUSessionResourceToReleaseListRelCmd.list.count
Integration: `2025.w14` (part 1)

There are 2 different definition of maxnoofPDUSessions (as per 3GPP TS 38.413),
one in NGAP lib (set to 16) and one in platform_constants.h (256 as per specs).
The NGAP lib definition is removed in this commit and replaced by the one
compliant with the specs.
This is fixing the warning:

Avoid access to mac->current_DL_BWP structure when scheduling DCI for
SIBs other than 1. This is not needed and can cause NULL pointer access
which can happen if the UE has released MAC configuration or has not
started RA yet.
Turn off any Nagle-like algorithm for SCTP
This means that packets will be sent as soon as possible and no
unnecessary delays are introduced, at the cost of more packets in the
network.

Refactor core network handling in CI, harmonize code
Prior to change set, there is a highly heterogeneous situation for core
network management in CI code: some log collection is done from groovy
files (when it could be done in python, which is easier for local
development), there are multiple commands to start a CN from XML files,
the code for starting a CN is always different (no one unified way to
start "any" CN), Ping/Iperf require some support in ci_infra.yaml, ...
To help with the above, refactor the handling of core networks in the CI
code as follows:
- define all CNs in ci_infra.yaml (basically how to deploy, undeploy,
collect logs, and on which node)
- make one Python class that reads from ci_infra.yaml and that allows to
start/stop previously defined CNs (and add unit tests...)
- make one XML command for start/stop of CNs, leveraging above class
- leverage the CNs defined in ci_infra.yaml consistently in
Ping()/Iperf()
- delete old code
Furthermore, the following supporting changes/bugfixes are done:
- repair Iperf2_Unidir() and add unit test
- fix a number of invalid escape sequence errors (there are some
remaining, which I will do soon)
- various bug fixes
- remove unused XML steps
Fix: Correctly Read PDU Address IE
The QoS Rules loop correctly moves msg pointer allowing the PDU Address
IE to be read correctly. The PDU Address IE is only processed if it is
provided, otherwise there is a warning.
Closes#931
Add enc/dec lib and unit test for 5GS NAS Service Accept
- add new files for Service Accept fgmm_service_accept.c/.h containing
the enc/dec functions (8.2.17 3GPP TS 24.501)
- enabled compiling
- add unit test
- add handler in stack
This is a hack. With some UEs/CN combinations, PDU session requests
might come in quick succession. Since 38.331 asks us to only have one
reconfiguration at once, we need to delay a second, third, ... PDU
session request until the first has passed, to make one reconfiguration
at a time.
The following cases are covered
- we have a regex whose escape sequences are not to be evaluated in the
string, but given verbatim to the regex engine. Hence, mark them as
raw strings.
- some are parameters for the cmd.run() call, but the parameters are
wrong, so remove that
- there is a `\|` that is also to be passed verbatim

As parent. The second change has no escape sequence, but since it's also
a regex, mark it as raw for uniformity (it doesn't hurt either).

With the server object to be passed into ping test, it's not necessary
to either hardcode an IP address or provide a template. Instead, always
fill the IP address, which simplies the Ping() code.
Verify that we don't have an IP address/hardcoded by throwing an
assertion.
38.413 section 8.2.1.4 says that if PDU session resource setup req
contains an existing PDU session, that one should be reported as failed.
That is rather complicated for us to do; simply reject all PDU sessions
and let the core deal with that.
If two PDU sessions are to be setup, the CU-CP sends two bearer context
setup requests. When running only the CU-UP, we inconditionally tried to
set up the CU-UP UE ID identifiers upon reception of the bearer context
setup request, leading to an assert. Check if the IDs are not already
set up, to avoid assertions in that case.
The REPORT service was hardcoded to only style 4, and therefore not easily extendable.
This commit moves the support for style 4 in a separate function.
Delete duplicated enum structs for RAN Parameter IDs for all the REPORT styles.
They are already defined in "openair2/E2AP/flexric/src/sm/rc_sm/ie/rc_data_ie.h".

Currently we still activated the DL HARQ process for PUCCH transmission,
and only at the time of the scheduled PUCCH transmission, we actually skip sending the ACK.
This is not only unnecessary, it is at least misleading and strange that
DL HARQ processes can be reused in the meantime, even though they are active...
Therefore simply don't activate the DL HARQ process by skipping the call to set_harq_status() if feedback for it is disabled.
