Anas Nashif 3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Istvan Bisz 26e6162a82 cmake: Eclipse CDT4 generator amendment
1. The generator handles just the COMPILE_DEFINITIONS.
   (See: __ZEPHYR_SUPERVISOR__)
   For the defines in INTERFACE_COMPILE_DEFINITIONS
   a special handling is necessary.

   Solution:
   The amendment function generates a macro header file
   ${CMAKE_BINARY_DIR}/zephyr/include/generated/cmake_intdef.h
   based on INTERFACE_COMPILE_DEFINITIONS and appends the
   defines from the file to
   CMAKE_EXTRA_GENERATOR_C_SYSTEM_DEFINED_MACROS.

2. Eclipse CDT4 indexer has problems with CMake 'Eclipse CDT4 - x'
   generator projects that use mixed C/C++.
   The Eclipse CDT4 indexer is showing a lot of unresolved symbol
   errors, when the project was created with CMake generator and
   the code is a mix of C and C++.
   The root cause of the problem is the g++ built-in __cplusplus macro,
   that is passed by CMake generator in the '.cproject' file.
   The defines in '.cproject' are always the same for C and C++.
   In mixed C/C++ projects, the header files often contain the following
   lines to let C++ code call the C functions:

   #ifdef __cplusplus
   extern "C" {
   #endif

   < header content >

   #ifdef __cplusplus
   }
   #endif

   Whenever the Eclipse CDT4 indexer compiles the code for
   code analysis, it has the macro __cplusplus set,
   independent of whether standard C or C++ source files are compiled.
   The 'extern "C"' confuses the standard C compilation and the indexer
   is messed up.

   Solution:
   The amendment function deletes the __cplusplus entry from
   CMAKE_EXTRA_GENERATOR_CXX_SYSTEM_DEFINED_MACROS.

3. The amendment function appends the defines from
   ${CMAKE_BINARY_DIR}/zephyr/include/generated/autoconf.h to
   CMAKE_EXTRA_GENERATOR_C_SYSTEM_DEFINED_MACROS.
