- use bearer-1 in compute_t of integrity NIA2
- compare integrity at the right place in nr_pdcp_entity_recv_pdu
- proper handling of security parameters settings (algos, keys)

Modify configuration of NGAP and NAS messages to comply with OAI CN configuration according to Fujitsu patch

-Hardcodings to be removed later when the NAS extensions will be integrated for OAI UE

Merge branch 'NR_SA_F1AP_5GRECORDS' of https://gitlab.eurecom.fr/oai/openairinterface5g into NR_SA_F1AP_5GRECORDS

This commit implements integrity and security settings for nr pdcp. It will
only work for SRBs.

This commit has not been tested. It may fail to work completely. To be checked.

added n1L1_stats.log. improvements to noise level (PUCCH/PUSCH) and signal level (PUCCH) computations. added DTX detection parameters for PUCCH/PUSCH/PRACH in L1 section of configuration file. hotfix from C. Roux for SRB PDCP integrity. extra logging to debug missing PUSCH/DCI at UE.

extra logging for PUCCH power control, DL NAS debugging. Fixed issue with power control configuration parameterss (pucchSNRx10,puschSNRx10) which were not read in properly. Consequence of moving them from the RRC setion to MAC section.

applied patch for UE PUCCH TX from Albesmart. changed p-NR-FR1 to 0 (from 20) to reduce SNR on UL. PUCCH is now functional after inserting physicalCellGroupConfig (before and after applying MasterCellGroupConfig)
