- bladerf depends on UTIL via common_lib.h
- use header guards

- Add CMakeLists.txt to build all T tracer user tools
- Previous Makefiles are retained in common/utils/T: you can do
  $ cd common/utils/T/tracer
  $ make # all executables are there
  or also
  $ mkdir build && cd build
  $ cmake .. -GNinja
  $ ninja T_tools # all executables are in build/common/utils/T/tracer

- Fix memory leaks detected by ASan
- Initialize variables that are flagged by compiler
- C struct initializer: x:y needs to be .x=y

We disable for two reasons:
- in the CI, with clang, it did not build once, but I cannot reproduce
  locally (even with clang)
- we want to maintain to be able to build without T tracer, so in one
  pipeline, we have to build without it. What a lucky coincidence!

USRP code uses the logging module, which has a dependency on T, if
configured. Therefore, include UTIL to satisfy this dependency

- UTIL: has LOG which brings as (public) dependency T, so link it publicly
- Move T to top to ensure all targets can have it

 * New folder named  XNAP created inside openair2
 * Added ASN File(38423.asn) for XNAP  and .cmake(38423.cmake) for the same inside XNAP.
 * CMakeLists.txt files changed to support .C and .H file generation for XNAP

commit ddf549b1 moved the CMakeLists.txt
for building radio libraries down to radio/. Previously, each option
would also declare a constant (e.g., OAI_USRP for USRP). With the
definition being below radio/, the executables don't have that define.

This commits removes the couple of defines that were in place:
- one that only shows a log, but it also applies for e.g., rfsimulator.
  It is also missing in the CI. Simply put it back
- two other places guard a commented(!) function call, which can go out
  entirely
