Harmonize nr_gold_pusch() and nr_gold_pdsch(), as the gold sequence
calculation for PUSCH and PDSCH is the same.

Add gold sequence cache with dynamic size, private to each thread. It
periodically reorders by call rate. To free the gold sequences after end
of life time of a thread, use the pthread API.

* !2749 immediately reuse UL/DL HARQ ID and don't wait for feedback if disable_harq == 1

* number of configured SRS antenna ports M <= N (number of physical antenna ports)

gNB: refactor code to handle end of using a specific HARQ process - finish_nr_dl_harq() and finish_nr_ul_harq()

* the mismatch between UE capabilities, passed to PHY by NFAPI PDU, and --ue-nb-ant-tx
  causes a segfault in SRS modulation
* issue with indexing txdataF[p_index], which fails due to an out-of-bounds access
  since first dimension of txdataF is sized based on ue->frame_parms.nb_antennas_tx
* N_ap used in SRS modulation is based on the number of antenna ports
  in the SRS configuration (srs_config_pdu->num_ant_ports)

sched_ul_bytes is reduced already in case the last HARQ round fails through handle_nr_ul_harq() -> abort_nr_ul_harq().
Therefore, the reduction in nr_rx_sdu() is wrong, and btw. it wrongly assumes the max. UL HARQ rounds to 4.
So simply remove this peace of code in nr_rx_sdu().

sched_ul_bytes tracks the volume of in-flight data.
When data is successfully received, sched_ul_bytes is decreased in nr_rx_sdu().
In case of reusing HARQ processes, the tb_size stored there is not correct.
Therefore use the actual SDU size instead.

gNB: add config file option "disable_harq" and set pdsch_servingcellconfig->ext3->downlinkHARQ_FeedbackDisabled_r17 accordingly

Don't break after first occurence of status template (interval "0.0- 1.0 sec").
With this modification we get final result, which is at the last line of log
(for interval "0.0-30.2 sec").
