Melissa Elkadi 9b16c1d860 Merge branch 'eurecom-develop' into episys/merge_nsa_w_develop 
At this point we are successfully able to build.
Additionally, we can run the scenario,
however, it does not pass. It seems that the gNB
is not connecting to the proxy correctly. Just
wanted to push the progress so far. FYI, the items
that had to be changed to correct the linking issues
were the following:

 - mac_rrc_data_ind_ue vs. nr_mac_rrc_data_ind_ue
 - rrc_data_req vs. nr_rrc_data_req
 - mac_rrc_data_req_ue vs. nr_mac_rrc_data_req_ue
 - rrc_data_req_ue vs. rrc_data_req_nr_ue
 - rrc_data_req vs. nr_rrc_data_req

The listed functions should be declard in the LTE/NR
UE directory depending on the functionality. Several
were mixed. i.e.: LTE functions being called in NR UE.

Also, removing siWindowLength, siWindowLength_int,
SIBType, SIBPeriod, and siPeriod_int from the NR UE RRC.
These variable were not used in the NR UE and are defined
for LTE only.

Lastly, in the NR_IF_Module.c of the NR UE, the global
variable def_dci_pdu_rel15 is not accessible. Need to
revisit this. For not it is commented out.
