- 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)

This reverts commit 19ba8dd7

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

MR !1079 / MR !1108:
1. Read slots from config file and schedules all slots *except* for slots 0 and 10. This is not a problem, since currently we cannot allocate more than six HARQ feedbacks in a slot, but we might have up to 7 with current configuration

2. phytest mode is configurable. From `nr-softmodem -h`:

   -m: Set the downlink MCS for PHYTEST mode
   -t: Set the uplink MCS for PHYTEST mode
   -M: Set the downlink banwdwidth (in PRBs) for PHYTEST mode
   -T: Set the uplink banwdwidth (in PRBs) for PHYTEST mode
   -D: Bitmap for DLSCH slots (slot 0 starts at LSB)
   -U: Bitmap for ULSCH slots (slot 0 starts at LSB)

3. Scheduler prints more information: UE PHR, PUCCH SNR, PUSCH SNR, RSSI
4. The scheduler learned to scheduler DLSCH/ULSCH in mixed slots (if the time domain allocation matches the mixed slot)
5. The scheduler expects
   * PDSCH Time Domain allocation index 0 to be the DL slot allocation
   * PDSCH TDA index 1 for Mixed DL slot
   * PUSCH TDA index 0 for UL slot
   * PUSCH TDA index 1 for Mixed UL slot
   * PUSCH TDA index 2 for Msg.3
6. Some more cleanup, e.g., separate PDSCH/PUSCH data structures into "semi-static" data (e.g., TDA allocation to use, since it changes seldomly) and "dynamic" data (e.g., RB allocation per slot, which changes every slot)
