fhstate is only used in the ETHERNET library, so move it to a smaller
scope. In AW2S it is write-only, so we can remove it.

These fields are only accessed from the ETHERNET library, which has a
dedicated ethernet struct (which is in device->priv). Move in there to
reduce visibility.

This function can be used to convert a timespec struct to a
openair0_timestamp. It can be used to synchronize the realtime
clock to the device sample number.

The original error was simply "failed to write to RF", which is not very
precise. Update with sample numbers for context, and add it in another
similar case for consistency.

Remove L1 dependence from NR band number
L1 band information relied on get_band function that couldn't provide an
unambiguous result. Also there is no SCF compliant parameter for L1 and
generally we don't really need that information in L1.
The MR also remove a RU section that used nr_band but was never really
accessed in NR.
Prior to this commit, constants NB_ANTENNAS_RX/TX are provided on the
command line to each compiler invocation. This has the drawback (1) that
also files that don't need that get the constants, and (2) it is not
easy to find them using ctags or similar, as the only definition is in
CMakeLists.txt (where it is not found).
In this commit, use cmake configure_file() to write a header file with
these constants. The file will be generated during cmake invocation, and
written to <build-dir>/common/cmake_defs.h. The relevant files that
need this definition will pick it from the header.
This has been used previously also in a commit to write git information.

semi-manual remove of not used #define commands
As i was upset to see all these #define with no code under, i made a
global pass to remove the obvious cases semi-manual remove of not used
bodies
manual script, then a lot of manual review
grep -IRs "#define" ../openair* ../common/* ../executables/ ../nfapi/ ../radio/ | \
fgrep -v '(' | fgrep -v '//' |awk '{print $2}' | egrep -v "#define *$n"| \
while read n ; do
grep -IRs $n ../openair* ../common/* ../executables/ ../nfapi/ ../radio/ | grep -v "#define *$n" | grep -q $n || echo $n;
done
will give a decent list of #define never used. Then, I think we should
keep lists of # define when it comes from standards, even if the code
doesn't use it right now
Rfsimulator beam reception/transmission
A simplified beam switching simulation for rfsimulator. This works
mainly in 1 gNB - N UEs scenarios. This is not a real beamformer with
antenna, channel and propagation model. The way it works is that the
peers inform each other about the beams they transmit in, and on
reception before channel modelling, the beam data is combined based on
preconfigured rx_beam/tx_beam gain matrix.
Usage:
- Add --rfsimulator.enable_beams to enable beam simulation
- Add --rfsimulator.beam_gains .
Example list: 0,-5,-10
Resulting matrix:
[[0, -5, -10] [-5, 0, -5]] [-10, -5, 0]]
- Add --telnetsrv if you want to control the beams manually. The command
in telnet is "rfsimu setbeam <beam_map>", where beam_map is a uint64_t
controling the reception beam and transmission beam. If the
application is switching the beams automatically the beams will be
overwritten as soon as the application chooses to switch beams.
Supports up to 64 concurrent TX and RX beams.
Allow arbitrary order of beam ids in set_beams2 function. This
allows the application to select any arbitrary order of beam ids.
The underlying transport mechanism still uses beam_map so the beam_ids
are ordered before sending.
Also replaced tx_beam_map/rx_beam_map into beam_map.
Also fixed an issue where --rfsimulator.enable_beams required an argument.
This function is to be called by the application to switch beams
on reception and transmission. When receiving new samples using
trx_read/trx_write the application is expected to be able to
determine which beam the samples belong to.
We assumed that PRACH FFT size is equivalent to PxSCH FFT size.
However, the parameter ru_config->fftSize is used for the C-plane Section Type 3
which is dedicated for PRACH and mixed numerology.
Based on the PRACH format, short or long, the PRACH values 256 or 1024
shall be filled.

2 functions with same name as static to make it clearer they are separate.
remove unused copy of log_level global var.
remove threequarter sampling variable from the radio board general
configuration. The decision of sampling rate is made above. A better
behavior can be done later, like ask to the radio board what sampling
rate it can do,then use it to decide the appropiate sampling rate from
the gNB configuration. In UE case, it is another issue, as the sampling
rate would change after we decode SIB1, but also it is not developped
yet.
B200 with high clock drift will go out of sync within 280ms which was
the default duration to sync in with iqrecorder. Now this value can be
specified via cmd line so the user can change it according to needs.
- removed some whitespace noise.
- cleaned up CMakeLists.txt
- reintegrated task_manager.c into thread-pool.c
- cleaned up some unnecessary code

By including the header. Also, move the definiton of the struct to the
MAC, where it is actually stored, and out of the radio common_lib.h,
since this is not a radio (split 7/8) parameter.
