an assertion fails in gnb (need to be fixed)

ENABLE_ITTI macro removal, modified telnet server to support all executables, modified record player to finalize switch to run-time option and allow usage with any device

nr-ip-UL-nos1: Integrate NR MAC PDU structures for the Uplink. Currently supporting only data SDUs, Control Elements to be added.

Signed-off-by: Raphael Defosseux <raphael.defosseux@eurecom.fr>

nr-ip-ul nos1: Small modification to be able to block the random traffic (which is generated when there is no Uplink IP traffic at the UE) at the MAC layer of the gNB

nr-ip noS1 uplink: Uplink IP traffic successfully received at the IP TUN interface of the gNB now. Logs cleanup.

nr-ip noS1 uplink integration (testing with RFSIMULATOR only): Uplink IP packets received at the gNB and reaching at pdcp layer. Asserion error at pdcp_fifo_flush_sdus when trying to write on the nas socket

Testing of NR PDCCH/PDSCH with RRC Configuration. added RRC configuration to NR UE. Updates to UE DCI procedures (moved to MAC) and updates to FAPI interfaces for UE. nr_dlsim is functional, added profiling information for gNB TX.

- nr_ulsim supports multiple DMRS configurations
