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.

changed DCI candidates to 4 for initialDownlinkBWP ue-specific searchSpace. ulsch/pusch stats added to nrL1stats.log

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)

corrections in PUCCH handling for dedicated configuration on initialBWP. first transmission handling for DL harq processes at UE.

- first PUSCH containing RRCSetupComplete not programmed for reception in PHY for some reason. DCI_0_0 received by UE.
- if RA fails, on the second attempt there is usually a crash (sometimes in L2_interface.c when getting UE context (added AssertFatal on this now).

-RRCSetupComplete successfully transferred to RLC of the UE now through SRB1, but not at the MAC yet.
-Needed to enable some additional elements for RLC config. at the gNB side (asn1_msg.c) so that the addition of the SRB does not fail at the UE.
 To verify if these are really required.

removed reading reconfig.raw with --sa. Also a segfault upon reception of RRCSetup-CellGroupConfig when this is not in the RRC context.
