It is very inconvenient to maintain an application that both runs on a
Zephyr board and an out-of-tree board.
It forces one to write build scripts like this in the app:
if(BOARD STREQUAL my_out_of_tree_board)
set(BOARD_ROOT some/out/of/tree/board/path)
endif()
To avoid this we change the semantics of BOARD_ROOT. Instead of it
being a path to the board root it is now a prioritized list of board
root directories. Zephyr will append ZEPHYR_BASE to BOARD_ROOT.
This ensures that Zephyr boards can be used when the out-of-tree board
directory can not supply the requested board.

They will no longer be available once the C Kconfig implementation is
removed.
oldconfig and allno/yesconfig implementations are available for
kconfiglib and could be added later if needed. savedefconfig (minimal
configuration generation) is available from the menuconfig.py
configuration interface.
cmake/usage/kconfig-usage.cmake becomes kinda pointless after this
change, so merge it into cmake/usage/usage.cmake.
Remove the kconfig_target, COMMAND_FOR_*, and COMMAND_RUNS_ON_WIN_*
CMake variables, as there's just the 'menuconfig' target now.

Fixes issue #7184.
Use $BOARD_ROOT to find correct list of supported boards.
This is needed since the user can set this variable to any directory.
Pass $BOARD_ROOT to usage.cmake where it is called.

$ENV{ZEPHYR_BASE} was recently search-replaced with ${ZEPHYR_BASE},
but some CMake code, like usage.cmake, is run by a seperate CMake
build system that does not have access to the CMake variable
ZEPHYR_BASE.
This patch reverts the usage of ${ZEPHYR_BASE} back to use
$ENV{ZEPHYR_BASE} in usage.cmake.
This has been proven to work on both Windows and Linux.

Instead of accessing the environment variable ZEPHYR_BASE every time we
require accessing the source code root, use an intermediate variable
that has OS path separators correctly set to '/' to avoid issues on
Windows.
Note: This removes the ZEPHYR_SOURCE_DIR CMake variable. External
applications using that will need to change to use the new ZEPHYR_BASE
variable.

Added posix to the list of arch's with boards. Usage will now show
native_posix as one of the available boards.

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
