If "utc_time" is selected, log lines are prepended with the UTC time,
formatted as YYYY-MM-DD hh:mm:ss.ssssss UTC.

The documentation has been updated. For other time methods, additional
description of what they show has been added.

Long PRACH extends beyond a slot. Changes necessary to mark future slots
that may contain prach in ru, phy and mac functions.

In RU, the PRACH IDFT is done only after receiving last slot and marks
for L1 to start processing. The L1 processes at the last prach slot and
reports to MAC with the first slot index.

In MAC scheduler, the VRB for future slots are also marked as used.
PRACH scheduler is called in advance one frame minus num prach slots.

Added uess_agg_levels configuration option which changes the number of PDCCH
candidates per aggregation level.

Use a common function for generating interface name. Use full interface
name in tun_if.h functions.

Also added support for 35Mhz, 45Mhz bw for 15Khz Subcarrierspacing
Referred Spec TS 38.101 v18.6.0 section 5.3.2, table 5.3.2-1

ran_func_kpm.c uses cp_ba_to_str(), but it is not defined in OAI. Define
it so we can link properly, instead of relying on FlexRIC (where it was
defined).

Useful to debug realtime issues, for example when calling a periodical
routine, if it's not programmed carefully enough, it may be that the first
call takes way longer than the next ones (for example it uses some memory
that is not mapped in the process, leading to many page faults the first
time it's executed).

Having a periodic log for the timing of this routine with min/avg/max/count
will reveal that a call is way longer than average and will help in
finding where exactly in the code the time is spent, thanks to the ease
of use of the T tracer; you put T(T_XX, T_INT(1)) just before the code
you want to measure, you put T(T_XX, T_INT(0)) just after and time_meas
will show the delta time between those events. Then you cut the routine
in smaller pieces, measure with T(1)/T(0), and you finally reach the small
guilty part that takes too long.

In time_meas.c, when getting 0 for the event, we log delta time with
previous 1 for the event. "start_valid" was not cleared, so receiving
a second 0 without 1 in between may lead to wrong logging.

Should not happen in practice, but still, little bug.

(Note: we don't protect against streams of 1, but this case should also
not happen.)

cleanup debug/dump flags by avoiding repetitions in the source code and
enable compiler checks. Add a help text if we set a wrong debug trace
option.

The idea to use atomic aligned to cache line for counting finished jobs
is reused, but instead of polling a semaphore was added

The parent commit cleans up and groups oai_exit in one place,
nr-softmodem-common.h. Therefore, this 5G file is included in the 4G
defs_common.h (at least it's mostly 4G), which is not nice. Instead,
define oai_exit also in 4G softmodem-common.h, and include this in
defs_common.h. Remove the cyclic inclusion of defs_common.h in
softmodem-common.h, and resolve all subsequent errors around unknown
types and extern definition mismatches.

This assert checks if the structure is correctly initialized. The structure
is one-time use so the assert is valid, but the value of the atomic was added
to the output to improve debugging.

This adds a basic telnet module to support the O1 interface at the DU,
to be used together with the oai/o1-adapter>. Concretely, this first
version supports to

- read/modify cell parameters
- stop/start the L1

Added a flush mechanism to actor thread. This is used to wait for all
waiting jobs in the queue to be completed.

 - removed some whitespace noise.
 - cleaned up CMakeLists.txt
 - reintegrated task_manager.c into thread-pool.c
 - cleaned up some unnecessary code

MIB, SIB1, random access and regular scheduling are traced.

At the beginning of a connection (rrc setup request and rrc setup), the
RNTI is reported as 0. Might be fixed, somehow, if absolutely needed (not
sure).
