Fixes one of the assertions when there is false DCI detecteted

Also added warning messages for gNB number of threads required

1.Changes to support multi slot parallel processing
2.Changes to run rfsimulator without multi-threading

dummy files cleanup

This reverts commit 85e1c34c.

This reverts commit 0280c083.

1. Changed FIFO types to threadsafe to ensure order of execution
2. Changed RB_NB_TH to 1 because PUCCH have some issues when running 2 slots in parallel (race). Dont know exactly where it happens.

Created separate job for PDSCH processing so that its exectued in the right order in rfsimulator mode.

MR !1054 : gNB_multi-threading_rework
-Replacing the existing multi-threading pipeline with threadPool library, simpler and more robust
-Updated dlsim to print stats to matlab file.
-Small fix for UE Ulsch coding.


MR !1063 : T_tracer__add_gnb_tracer
Minimalist gnb tracer to trace (for the moment) rxdataF when some decoding for PUCCH or PUSCH has been done

MR !1070 : nr_pdcp_improvements
Implement data transfer (38.331 5.2): - transmit operation (in nr_pdcp_entity_recv_sdu) - receive operation (in nr_pdcp_entity_recv_pdu) - t-Reordering expiration

MR !1076 : PBCHNRTCFIX
Issue Details: If bchPayload is changed to non-zero value, then the test case used to fail.
Solution: While final check against UE decoded bchpayload and input bchpayload, the AND operation with 0xff is missing along with RIGHT SHIFT operation for input bchpayload.


MR !973 : s1_subnormal
LTE update in S1 functions from Fujitsu.
-NNSF
-S1AP auto recovery.
-Handling unexpected messages.
-Fix memory leak.


MR !1048 : develop_SA_RA
-Draft and initial trigger of RA procedures upon SIB1 reception. 
-Improvements on SA SIB1 reception.
-Get Msg3 from RRC to MAC layer (this fixes random Msg3). 
-Fix Tables 7.4.1.1.2-1/2 from 38.211.

1. RX PBCH slot n
2. RX PDCCH slot n
3. Start TX PUSCH in parallel for slot n+6
4. RX PDSCH slot n
5. Join PUSCH
6. TX PUCCH slot n+6

when signal quality drops. when cmd line option used ue goes back to sync mode

CI: try to optimize the file system usage when building in the CI VM env. Increased the VM memory of one to allow linking

thread1: RX
thread2: TX

also harmonize configuration files some more

- FAPI structures not to be used as config_req at MAC since that FAPI is
  just for communication between MAC and PHY
- additional frame_type member added to the FAPI struct

- use LOG_D for debug logging

Fix nnsf selection.
Fix indentation and opening brace.
