  * 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

     -- 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

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.

For these reasons lsch_channel_level_median is introduced.
