In order to determine the number of RBs, the pre-processor needs to
calculate the TB size (as it depends on how much of data the UE actually
has to send). Before, the pre-processor would calculate this again,
which obviously is superfluous.

Note: in the DL, we do the same

nr_process_mac_pdu() gets the UE_id instead of the RNTI as parameter to
avoid to search the UE_id after nr_rx_sdu() did that already.

Since nr_process_mac_pdu() is only used/called from one file, remove
from the header file.

Reformat affected code to align more closely with OAI style guidelines.

Due to real-time issue, we might miss HARQ feedbacks. Similarly, I
observed that we get feedback for HARQ processes scheduled for a future
frame (don't know how this can happen).

This commit introduces a function that checks whether the first HARQ
process in the queue corresponds due the current frame/slot combination.
If not, it marks old feedbacks for retransmission.  Furthermore, it also
checks whether the feedback is too early, by not considering this
feedback.

-Support of 10MHz BW for 5G NR

MR !1013 : ptrs_rrc_config
-Remove hardcoding of DL and UL PTRS parameters at gNB and NR UE

add new nsa reference test

dummy files cleanup

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.
