This patch solves two different issues at the same time when building
with gcc/g++ 9.2.0:
1) The -fvisibility=hidden support check was done using the C++
compiler only (with check_cxx_compiler_flag), inside the block
corresponding to the C compiler being GNU/clang, and the result of
the check was applied to both C++ (CXX_FLAGS) and C (C_FLAGS) flags.
Instead of this, there should be separate checks for the C and C++
compilers, each of them modifying a single set of <LANG>_FLAGS.
2) -Wincompatible-pointer-types support check was done using the C++
compiler only, and the result of the check was applied to both C++
(CXX_FLAGS) and C (C_FLAGS) flags. But, this warning is not
applicable to C++ and actually breaks compilation when using g++ 9.2:
[ 0%] Building CXX object lib/src/asn1/CMakeFiles/rrc_asn1.dir/rrc_asn1.cc.o
cc1plus: error: ‘-Werror=’ argument ‘-Werror=incompatible-pointer-types’ is not valid for C++ [-Werror]
Instead of this, there should be a check for this warning only using
the C compiler, and therefore only modifying the C flags (C_FLAGS).
This patch splits the macro into one specific for C++ (which modifies
CXX_FLAGS) and one specific for C (which modifies C_FLAGS). And so,
the macro call to check for `-Werror=incompatible-pointer-types' is
made C-only, and the one for `-fvisibility=hidden` is done for both C
and C++ targets (each on the correct GNU/clang compiler block).
Due to how the tests are done in cmake, the '-fvisibility=hidden'
check wasn't even succeding before, so the compiler option wasn't
being effectively used. The cmake flags.make file contents throughout
the project are updated as follows now:
Before this change, we had:
C_FLAGS = -Werror=incompatible-pointer-types ...
CXX_FLAGS = -Werror=incompatible-pointer-types ...
And after this change, we have:
C_FLAGS = -Werror=incompatible-pointer-types -fvisibility=hidden ...
CXX_FLAGS = -fvisibility=hidden ...

move non-type-specific methods of proc_t to its base class.
procedure state machine was simplified via a future-type. Now procedures dont get stuck until the user reads the procedure outcome.
made the NAS procedures more event trigger/reaction-based.
