Adding missed changes in previous commit

MR1029 : Benetel driver update  
This MR fixes an issue with the driver for the 4G Benetel RRUs.
Power levels on the 5G side were adapted to avoid saturation of the signals. 
5G performance is now the same as with USRP. 
Support for 2 antennas for both 4G and 5G was added

MR1062 : fixing the RE offset for each Rx antenna in pusch channel estimation

It is sufficient to pass l_d directly to the function but considering future extension to mapping type B, this way makes more sense.

MR1046 : Add support for NR UL SC-FDMA up to 100 MHz

MR1053Nr : pdcp nea2 security

MR1049 : improve rfsim
-Fix a regression 
Earlier parameter reading was moved to an external thread,  
Eventually the check at the end of the main was too early, 
Declaration of  some extra parameters are now on command line
-Enhancement: 
use the rfsim as a server on UE side, so we can connect two xNB to one UE
-Simplification: 
remove rfsim flags that have been made for convergence with replay function in usrp driver, but this is useless as they changed their code
-Fix a bug in ubuntu 20.04 (now the code is ready in whole OAI)


MR1056 : Bugfix: NR BSR calculation
Fixes a bug in the scheduler for BSR calculation. 
Before, we might wrongly track the BSR of a UE and not schedule it anymore although it has data. 
Should be fixed now and improve UL throughput. 

MR963 : Nr mac multi rach global edge
-Handling of Multiple Users triggering RACH request in different RACH Occasions in same slot
-Providing Random Access Response according to RACH request

fixing the RE offset for each Rx antenna in pusch channel estimation
