MR2416 rework the ul_config_request data structure: put the mutex in correct place and encapsulate the struct management in access API, remove internal storage visibility

MR2416 split nr_ue_dl_indication in two different functions, that have little interaction: nr_ue_dl_processing and nr_ue_dl_scheduler. the call remain nr_ue_dl_indication

MR2416 split  nr_ue_scheduled_response in  nr_ue_scheduled_response_ul and  nr_ue_scheduled_response_dl. Make these functions code more readable

MR2416 Simplify interface by removing dcireq_t struct that was only calling one function and remove fill_scheduled_response that also fills only a struct in a complex way

MR2416 make frame/slot in ul_config dl_config instead of upper structures value, fix modulo computation of frame

Certain FH 7.2 use cases require 8 antennas, so make room to propagate
this down.

For the initialization of the xran library (split 7.2), we need some
parameters such as PRACH or frame config. However, to date,
initialization of split at level 7 use the split 8 openair0_config
structure, which does not have the necessary information.

Hence, add a single structure that contains that information.

* make a single call to various function
* make fill_rf_config() static, it is only used in this file
* do not initialize the number of antennas in openair0_cfg in
  init_NR_RU(), as it is already done in fill_rf_config()

Harmonize the call to openair0_transport_load(), by putting it in a
single place instead of multiple calls

Further, delay the call to ru_thread, for two reasons:

1) it is somewhat "symmetric" with local RF, which is done there as well

2) for the xran library, we need to read some parameters such as PRACH,
   frame format, etc. At the RU, the corresponding FAPI config request
   parameter structure is copied from the gNB to RU at the beginning of
   the ru_thread, so we have to wait for that to happen.

Reformat code to properly copy memory if we skip precoding.

precoding_stats timing is not part of ru->feptx_ofdm, but
ru->feptx_prec, so always print it.

Previously, in order to speed up processing if precoding is disabled, we
just copy the pointer from txdataF to txdataF_BF, as opposed to do a
full memcpy() to duplicate the data. The same happens if we cannot have
precoding, i.e., in SISO. This has implications such as memory leaks,
which is why this is not being done. However, the code comment is
intentionally placed there.

For 7.2 FH, some RUs do phase compensation, whereas for others, the DU
does it. In fact, this can be "negotiated" using the M plane. Since we
don't have the M plane yet, add a configuration option to set where
phase compensation is performed.

For certain processing, e.g., in the case of FH 7.2, we need to ensure
that critical L1 processing happens fast. Try to force speedy processing
with this high priority.

init_RU_proc() does not start the ru_thread, this is done by
start_RU_proc()
