This commit provides CSI reporting support
which is required for MIMO.  It also updates
the configuration files, provides sample BLER
simualtion files for packet dropping in the
MIMO 2x2 case. It also includes the hooks
and functions (e.g., updating UCI2_3_4 PDU field)
for MIMO 2x2 support. This commit will not include
any channel abstraction code or modelling.

- OPENAIR_DIR replaced with AWGN_RESULTS_DIR
- Copying UCI_2_3_4 PDU with rx'd PDU from proxy
- Reverting hacks/whitespace changes

For whatever reason most of the files had their permission
changed from 644 to 755, which is not wanted.

- remove size limitation of 307200 in trx_read_func (SYRIQ library)
- update to new openair0 interface  (./targets/ARCH/COMMON/common_lib.h)
- add gNB band22 configuration file (./targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band22.tm1.106PRB.adrv9371zc706.conf)

please read ./targets/ARCH/ADRV9371_ZC706/SYRTEM_IQ_QuickStart.readme for more details

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
91064382.

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.

 - added -a option to lte-softmodem for easier testing of different RF chains
 - added $OPENAIR_TARGETS/bin to path for easier access to init scripts
