Robert Schmidt 8107939f08 Change OAI license to CSSL v1.0 (and others)

- all RAN code, CI code, configuration files, dockerfiles, in CSSL v1.0
- all deployment code (openshift, charts, ancillary files like shell
  scripts), in MIT
- documentation in CC-BY-4.0
- exceptions might apply and are listed in NOTICE
- there is a new LICENSES folder with all licenses
- CONTRIBUTIONS.md has been updated accordingly

For automated changes based on OAI PL v1.1:

    perl -i~ -0pe 's/\/\*.*Licensed to the OpenAirInterface.*openairinterface.org\n#?/\/*\n * SPDX-License-Identifier: LicenseRef-CSSL-1.0\n/s' **/*.{c,h,cpp}
    perl -i~ -0pe 's/\/\*.*Licensed to the OpenAirInterface.*openairinterface.org\n#?/\/*\n * SPDX-License-Identifier: LicenseRef-CSSL-1.0\n/s' **/*.ts
    perl -i~ -0pe 's/<!--.*Licensed to the OpenAirInterface.*openairinterface.org\n.*-->/<!-- SPDX-License-Identifier: LicenseRef-CSSL-1.0 -->/s' **/*.xml

The rest (cmake, files with missing license, cmake) manually.

Environment variables

OAI uses/supports a number of environment variables, documented in the following:

NFAPI_TRACE_LEVEL: set the nfapi custom logging framework's log level; can be one of error, warn, note, info, debug. Default is warn.
NR_AWGN_RESULTS_DIR: directory containing BLER curves for NR L2simulator channel modelling in SISO case
NR_MIMO2x2_AWGN_RESULTS_DIR: directory containing BLER curves for NR L2simulator channel modelling in 2x2 MIMO case
OPENAIR_DIR: should point to the root directory of OpenAirInterface; BLER curves for LTE L2sim channel emulation
NVRAM_DIR: directory to read/write NVRAM data in (5G) nvram tool; if not defined, will use PWD (working directory)
OAI_CONFIGMODULE: can be used to pass the configuration file instead of -O
OAI_GDBSTACKS: if defined when hitting an assertion (DevAssert(), AssertFatal(), ...), OAI will load gdb and provide a backtrace for every thread
OAI_RNGSEED: provide a fixed seed for random number generators (RNG). If this variable is absent, a random seed will be read (from /dev/urandom).
USIM_DIR: directory to read/write USIM data in (4G) usim tool; if not defined, will use PWD (working directory)

Furthermore, these variables appear in code that is not maintained and maybe not even compiled anywhere:

HOST: alternative host to connect to, for CLI, if neither REMADDR nor SSH_CLIENT are defined
REMADDR: host to connect to, for CLI client
SSH_CLIENT: alternative host to connect to, for CLI, if REMADDR is not defined
USER: user name in the command-line interface
rftestInputFile: input file for the calibration_test tool
OPENAIR2_DIR : OMV and OMG modules, obsolete
TITLE: OTG module, obsolete
