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. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

cmake: Toolchain abstraction: C++ Introduce toolchain_cc_cpp_*-family of macros. Move the following into the toolchain_cc_cpp_* macros: * Common base set of flags * C++ standard version * RTTI * Exceptions These macros must be implemented by every compiler port. These macros set the respective flags, but leaves logic and control to the root CMakeLists.txt file. No functional change expected. Clang's C++ flags are compatible with gcc, and are thus inherited. This is motivated by the wish to abstract Zephyr's usage of toolchains, permitting easier porting to other (commercial) toolchains. Signed-off-by: Mark Ruvald Pedersen <mped@oticon.com>
