Problem:
- GTP-U logs showed negative TEID values (e.g., -1943516315) due to signed/unsigned
conversion. Due to wrong conversion from uint32_t to int and overflow caused negative values.
- TEID values were inconsistently formatted across different log statements, due to
mixed use of %d, %u, %x formats for TEID logging. Made debugging and troubleshooting difficult

Changes:
1. Fixed signed/unsigned conversion bug: use teid_t. Prevents overflow when TEID values exceed int range.
2. Standardized TEID logging format: all TEID values now use '0x%x' hexadecimal format.
   Consistent 'TEID' capitalization throughout

The previously introduced function rrc_release_rlc_entity has been
adopted to deactvate the RLC entities after release.

Do not add PDU Session with status higher than PDU_SESSION_STATUS_TOMODIFY
which means, do not add "failed" or "to release" PDU Sessions.

According to TS 38.463 - clause 9.2.2.4 and 9.3.3.12.
Also, fix response message by encoding choice IE only
with presence of modified PDU sessions.

CI: Add unified Jenkinsfile for all test pipelines

This MR introduces a single Jenkinsfile to cover all current CI test pipelines
Improvements:
- correct reporting of the start timestamp in the HTML report
- harmonize log collection - always collect as test_logs_${env.BUILD_ID}.zip

Combine Jenkinsfile and Jenkinsfile-oc from parrent commit into a single
file.

Fix unsigned to signed decoding parameters to allow for 'no affinity'/'no pin'
threads to CPUs

By default, 'L1_rx_thread_core', 'L1_tx_thread_core', 'ru_thread_core' are set
to '-1' but the values were decoded from config file as unsigned instead of
signed types, thus, it was not allowing to set them with '-1' from config file.

PRS bug fix and CI Integration

- Fix the bug in PRS channel estimation while copying memory to compute the
  impulse response
- Integrate PRS testing to CI

Simplify node management in CI, handle SIGINT

- Make a single <node> XML step entry common to all XML steps to harmonize code
- Handle SIGINT to make it possible to more easily stop the CI script.

Bugfix: save old tunnel info to remain the user plane connection while rolling
back to source DU due to handover failure

This MR closes issue #984 that UE lost the data plane connection while rolling
back to the source DU due to handover failure.

NR UE: fix PDCCH LLR indexing for different search space RB sizes

After !3603 (merged), when multiple search spaces have different CORESET
configurations (different number of RBs), the LLR buffer stride must be
calculated based on the maximum RB size across all search spaces, not the
current search space's RB size.

The LLR buffer is allocated with size based on get_pdcch_max_rbs(), but the
demapping function was using coreset_nbr_rb (current search space) for symbol
stride calculation, causing incorrect LLR extraction when search spaces have
different RB configurations.

This MR tries to fix it.

Closes #1021

By default, 'L1_rx_thread_core', 'L1_tx_thread_core', 'ru_thread_core' are set to '-1' but the values were decoded from config file as unsigned instead of signed types, thus, it was not allowing to set them with '-1' from config file

Use the bash script from a parent commit to verify PRS functionality.

This commit inputs several distances at once and obtain the summary of
successful and failed tests. We look for the number of successful tests
that are geater than 0. We do that here since we sometimes dont receive
a response for a telnet command from the rfsim although the command
is applied. This is related to the queing telnet commands in the rfsim.

The script for the distances 50, 100 and 150 are called as follows,

./set-and-verify-distance-prs.sh 50 100 150

The summary can be viewed as follows,
==================== SUMMARY ====================
Total tests run : 3
Successful tests: 3
Failed tests    : 0
=================================================

Set RFsim (DL) distance and use PRS to estimate the new distance. This
is verified by comparing the distance set in RFsim with the distance
reported through ToA estimation at the UE.

Note that since RFsim telnet output is asynchronous (it uses a queue
internally), we use grep --max-count 1 to wait for the matching line,
together with ncat --idle 0.3 to keep ncat open for some time. The
--max-count option will terminate grep after the first occurrence. For
this to work reliably, we need to use grep <(echo | ncat) as opposod to
simply echo | ncat | grep, as the latter does not seem to reliably
make grep exit after the occurrence.

Protect with mutex to allow reading from another thread.

In a future commit, we will look up the maximum ToA over the last
transmissions. Introduce a buffer in which we write the last
16 measurements.

When multiple search spaces have different CORESET configurations
(different number of RBs), the LLR buffer stride must be calculated
based on the maximum RB size across all search spaces, not the
current search space's RB size.

The LLR buffer is allocated with size based on get_pdcch_max_rbs(),
but the demapping function was using coreset_nbr_rb (current search
space) for symbol stride calculation, causing incorrect LLR extraction
when search spaces have different RB configurations.

Handle SIGINT and mark any subsequent steps as failed. Receiving SIGINT
a second time will abort the script immediately (as is the case before
this commit).

Note that Python seems to relay the signal to the "controlled" process
(e.g., Ping), which would return immediately with an error. So some
steps like Ping will abort immediately, others (e.g., IdleSleep) will
finish their step, and then the present logic will mark subsequent steps
as failed.

"or None" would assign if the first term is false-y. But not specifying
it would already lead to the variable being set to None.

All XML steps take a single node. We can thus "centralize" reading this
parameter in the main loop and pass it to ExecuteActionWithParam().

Some CI tasks/commands like Iperf(), Ping() get multiple nodes (via XML
parameter "nodes") to potentially run UEs on different nodes (hosts) at
the same time. However, I argue that this is not good:

- we don't actually use this -- where we specify multiple UEs, it's
  always "localhost localhost..."
- it is inconsistent, as we typically have a single "node", not nodes,
  and there is a possibility to harmonize (see also next commit)
- if we needed it, there would be better ways to achieve the same.
  First, for hardware-based UEs, the ci_infra.yaml can specify different
  UEs. For simulated UEs, it would be feasible to have multiple XML
  steps run in parallel, e.g., in the XML <parallel> tag, which would
  clarify that multiple UEs on different hosts run in parallel
- it reduces code.

Hence, make a single <node> for these XML steps.

Created Jenkinsfiles:
- Jenkinsfile: for stadard test pipelines
- Jenkinsfile-oc: for deployments with OC

These 2 Jenkinsfiles covers all current test pipelines.

Previously, we were using int16_t for the variable ch_tmp which was later harmonized to use c16_t while leaving <<1. This introduced the bug while accessing the address of the element at first_half of the ch_tmp variable.
