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

 - 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).

Add actor library which implements the Actor model (see  https://en.wikipedia.org/wiki/Actor_model).

Implement run-to-completion for processSlotTX. This is achieved by using a new
dynamic_barrier_t which allows to specify callback after the first join has been
made.

This commit introduces dynamic_barrier_t. Its a thread barrier that counts joins
but allows callback to be specified later. See std::barrier for a basic barrier
description.

Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP TS 38.101-5
Conf files added for 15Khz, 5Mhz and 30Khz, 10Mhz configurations added for these bands

telnetsrv uses the Intel/AMD-specific "cpuid" instruction, which is not
available on ARM machines. Remove the call.

The previous code was checking for the number of cores, which is
retained by a call to get_nprocs(). I did not find an equivalent for the
number of threads in C. In C++, there would be
https://en.cppreference.com/w/cpp/thread/thread/hardware_concurrency, in
case it's relevant for anybody.

This changes the way T_IDs are defined. The T_ID macro was using a integer to pointer cast in
order to provide type safety. This trick disables some compiler optimizations, as explained
here: https://clang.llvm.org/extra/clang-tidy/checks/performance/no-int-to-ptr.html.
Removing the type cast reenables the compiler optimizations.

Since long long is the bigger type ( 8 bytes ) of the two used ( long long and uint32_t ),
and long long is also available on ARM, change this parameter to always have this type.

This allows to always use format specifier '%lld' in the logs that use TICK_TO_US, which would otherwise return long long or uint32_t depending on architecture.

CodeChecker is a python application that collects reports from static analyzers like
clang-tidy, clangsa, cppcheck.
