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.

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.

Handle the case of precoding in allocation of the txdataF_BF structure
accordingly.

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
precoding 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()

While testing the OAI 5G RAN in SA mode, it appears that the PDU session
establishment request is using the wrong security header type.

The current used header is: "Integrity protected and ciphered with new
5G NAS security context".

However, according to TS 24.501, Table 9.3.1, this header can only be used
by the "Security mode complete" procedure.

Changes:

 - Hence, the new security header has been changed to "Integrity protected
   and ciphered", which will use the security context generated during the
   "Security mode complete".

 - Sequences numbers and NAS counters have been updated to reflect that
   change.
