* added banner to pipeline script
  * added parameters to Jenkins pipeline / python
    * xmlfile and test stage
  * eNB configuration files are located under ci-scripts/conf_files
    * no more correction of MNC
    * still correction of EPC / eNB IP addresses at runtime
    * Initialize_eNB_args is back using the proper "-O " syntax
  * Terminate stage is parallel as in FJU's original pipeline
  * Log collection stage is back fully parallel
  * Console as artifact an option
  * Check if terminate calls ended well, to be repeated at the end
  * Adding back iperf:
    * selection of iperf vs iperf3
    * adding some iperf testcases to test suite
  * Better enb launch

  -- Jenkins Pipeline script:
     -- Moved the node to a proper subnetwork
     -- Added ansiColor option
  -- XML testsuite file can now be an option to the main.py python script
     -- Added some examples testsuite templates
  -- main.py python file
     -- Added an option when opening an SSH session: taking care of clients with copied SSH keys
        in that case, verifing that we are on the correct host
     -- BuildeNB method is closer from Fujitsu's original one
        improvement on flexibility for code source path naming
        better clean-up of workspace
     -- LTEBOX EPC (init / termination / logCollection) methods improvements w/ a /tmp path
     -- Checking of processes (EPC / eNB) is parallelized
        also handles LTEBOX EPX vs OAI CN
     -- UE methods added: attach, detach, reboot, ping
        With complete parallelism for multiple UEs
        iperf added but not tested

     -- build on a server with RF HW capabilities
        for the moment USRP B2x0
        also handles merge request process for gitlab
     -- since it is for CI, it is a clean build
     -- connect to an EPC (OAI or LTEBOX)
     -- terminates eNB / EPC

Summary of changes:
- RF simulator enhancements
- remove oaisim
- use new asn1c
- bug fixes / cleanup
  - TDD fixes
  - IQ replay fixes
  - clean VCD/LOG_XX

The new asn1c requires a reinstallation.
Do:
    ./build_oai -I

The power estimation of the UE has to be debugged (calibrated?).
In the meantime, using "--ue-rxgain 140" lets the UE and eNB
talk to each other in the basic simulator.

2. minor modifications in dlsch_demodulation.c for 2 eNB TX antennas, 1 RX antenna. Inconsistant indexing of some arrays in this case.
3. change in config_load_configmodule.c : removed exit(-1) when no configuration file is used. This makes unitary simulators exit. Effect on lte-XXsoftmodem TBC.

- use OAI location to retrieve asn1c
- use a specific commit instead of a branch name

This was used for the ITTI analyzer.

The ITTI analyzer is now to be considered obsolete.
The source code will be removed at some point.

receiver. THe proposed solution is to replace the average channel level with
median  = (max+min)>>1.
For these reasons lsch_channel_level_median is introduced.

instead of _mm_srai_epi16
_mm_srai_epi32 should be used as _mm_madd_epi16
packs multiply-adds 16 bits and packs into 4
blocks of 32 bits.

Log review step 1: legacy VCD removal, LOG macro modified, TTracer enabled at build time by default, in a way it, by default configuration,  provides console logs, as in previous versions

Add `autoreconf -iv` in build_helper to create configure file for asn1c.

1. It's no need to modify LTE-RRC's ASN.1 file for enabling option group
   feature in generate_asn1.
2. It's no need to patch the C header files generated from
   LTE-RRC/S1AP/X2AP's ASN.1 in fix_asn1.
3. It's no need to pre-process S1AP/X2AP's ASN.1 for enabling information
   object class feature by asn1tostruct.py.

This commit requires an un-official version of asn1c which are
collaboration of asn1c community members and `build_helper` is modified
in this commit accordingly :

  https://github.com/brchiu/asn1c/tree/velichkov_s1ap_plus_option_group

This asn1c can also convert ASN.1 of 5G NR RRC (38.331, v15.1.0) and
generate C files with -findirect-choice command line option without
tweaking ASN.1 file.

Examples for how to use this asn1c for S1AP are in S1AP files, e.g.
s1ap_eNB_nas_procedures.c and s1ap_eNB_handler.c.

There is an modified openair-cn (based on tag 0.5.0) with this new asn1c at :

  https://github.com/brchiu/openair-cn/tree/new-asn1c

Basic S1AP interaction and data transfer operation between OAI eNB and
this modified openair-cn has been tested.

Note: Community version of asn1c is keeping evolved to provide better usage.

fix: avoid assertion when terminating lte-softmodem process.
