  * 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

Since now pucch_n1_AN is taken from the configuration file,
it has to be set to 0. Value 32 will not work well, at least
in FDD. This has to be handled properly at some point
(do not use uplink resource blocks used by PUCCH for PUSCH).

It was not possible to merge the branch directly, because the
history of this branch contains files that cannot be in the
repository, namely wireshark from Cisco work on nFAPI.

As for Cisco work on nFAPI, a special commit containing all the
work is thus created.

Below is the output of the command:
git log --graph 184d51c6..61276d87

184d51c6 is the commit ID of the develop
branch prior to the merge.

61276d87 is the commit ID of the
nfapi-L2-emulator branch prior to the merge.

The commit 61276d87 (and all its
history) will be removed from the main OAI repository. It is
present in the internal OAI repository for those who have access
to it.

There was also some cleanup done on the code.

Some changes were necessary to have the eNB functional. They may have an
impact on the FAPI ...

'_' is not a valid character.

S1AP specs say:

    ENBname ::= PrintableString (SIZE (1..150,...))

And X.680 (08/2015) 41.4 table 10 lists the valid characters for
PrintableString. '_' is not there. We replace by '-' which is there.

Connection of eNB to ppenair-cn has not been tested. There is no reason
why it would fail.

This commit fixes issues introduced by the previous commit.

Summary of work:
- cleanup:
  - fix LOG_XX to be less verbose
  - fix cmake_targets/CMakeLists.txt
  - fix oaienv
  - remove dead code
- bug fixes:
  - in openair1/SCHED/fapi_l1.c we had:
      eNB->pdcch_vars[subframe&1].num_dci           = number_dci;
    should be:
      eNB->pdcch_vars[subframe&1].num_dci           = 0;
    This bug let the PHY send more DCIs than what should have been
    sent because num_dci is incremented later on in the code.
    This fix may be a problem for fapi mode, to be checked.
  - add new T VCD traces
  - revert openair1/PHY/TOOLS/file_output.c to 'develop' version
  - remove thread_id in logRecord/logRecord_mt
  - revert (and adapt) configuration files
  - be careful when doing frame++, we need to % 1024
  - revert target_rx_power in openair2/LAYER2/MAC/eNB_scheduler_ulsch.c
- NFAPI:
  - the open-nFAPI code has been included in the repository. See nfapi/README.
    Maybe we should "git clone" the Cisco repository instead. We have to be
    careful of availability though.

What has been tested:
- monolithic eNB FDD 5/10MHz with one UE, iperf UDP/TCP uplink/downlink

Anything else may fail to work, especially the FAPI mode, which has not
been tested at all.

It has been chosen to not include the full history of commits
from David. He included a binary version of wireshark, probably
a modified one that understands NFAPI. Wireshark is released under
the GPL license, we cannot include it in the repository. We could
have done a next commit to remove this binary. But then it would
still be present in the history of commits, which may not be allowed.
And it would take space on disk. We could edit the history to remove
wireshark entirely. But this operation is too complicated.

There was also a pcap capture file, which has nothing to do in
the history of commits and would take space on disk. There again,
it's too difficult to edit the history to remove it.

There was a file .gitignore that was also removed.

The original history can be found on David's repository:
https://gitlab.eurecom.fr/daveprice/openairinterface5g/
The branch is: nfapi-ru-rau-split.

A copy of that branch has been included in the internal OAI
repository, for those who have access to it.
The branch is the same. The last commit ID is
9106438239e0bc626ff1fa1d97d911caadd0fbb9.

You can compare the current commit with the commit 9106...
to see what differs.

The current commit has to be considered non-working.
The commit following the current commit will fix problems with
the work in the current commit.

If you use git bisect, don't spend time analyzing the current
commit.
