Merge branch 'nr-ip-over-LTE-stack' of https://gitlab.eurecom.fr/oai/openairinterface5g into nr-ip-over-LTE-stack

Added Rx indication for DLSCH type and resolved issue with MIB decoding while sending DL IP traffic. Data packets still not parsed properly at the UE MAC layer.

Alldownlink IP traffic is transferred consistently from the gNB to the PHY of the UE now based on testing with the RFSIMULATOR. Slight extension in FAPI interface required to move the received data to the MAC layer of the UE.

Downlink IP traffic flow using LTE RAN stack over NR-PHY. Downlink traffic reaching PHY of gNB now using the noS1 mode. Extensions required for the reception through the LTE RAN stack at the UE side.

Merge remote-tracking branch 'origin/Develop-nr-threequarter_fs-80mhz-x310' into integration_2019_w18

1. Fix code generated from ASN.1 of F1AP v15.4.0 failed to be compiled
2. Fix incorrect UPER encoding for empty extensible SEQUENCE in 38.331
3. Fix the problem that duplicate type names exist in OPEN TYPE

The changes made in this branch is to enable -E(threequarter sampling rate) option for mu=1 and 217PRB(ie; 80 MHz) to run on USRP x310.

Final --phy_simulators warning removals for this branch, and former polar coding function corrections

--phy_simulators warning removals, except for nr_dlsim. Polar coding old implementation's approximation and a priori information options needs to be corrected or removed
