Aurelien Jarno a0b9e70e10 c++: kconfig: EXCEPTIONS needs to depend on NEWLIB_LIBC
C++ exception support needs to use the newlib C library in order to get
the abort function. C++ exceptions also do not work with the simple
malloc/free implementation provided by the Zephyr minimal C library.

Benoit Leforestier 16451850e7 C++: Fix vtable with libstdc++
__cxxabiv1 is an internal namespace used by GNU's libstdc++.
When linking with C++ standard library (libstdc++),
__cxxabiv1::__class_type_info is already defined inside.
If user code contains virtual classes,
__cxxabiv1::__class_type_info is defined twice.

Sebastian Bøe f9b2da37b0 kconfig: Move CPLUSPLUS from root to "Compiler Options"
Enabling C++ support for the application has been inappropriately
located at the root of the Kconfig menu. The root should be kept as
clean possible to allow easy navigation.

This commit moves CONFIG_CPLUSPLUS into

~/"Build and Linker Features"/"Compiler Options".

This is a purely cosmetic change and does not change the
'visibility' (depends) of the Kconfig option.

Arguably, it would fit better into

~/"Build and Linker Features"/"Language Options"

but this entry does not exist.

Michael Hope 7383814d8b cpp: mark __dso_handle as weak.
The POSIX target uses the native crt0 which already provides
__dso_handle.

Sebastian Bøe 12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make

Anas Nashif da7cc84655 subsystem: cleanup misc and make cpp a subsystem
Move a way from misc/ and put in its own subsystem to allow enhancements
in the future and make it a core part of Zephyr, not just something
misc.
