The end_sema k_sem was only initialized on one of the several paths
that used it, leading to some crazy clobber-the-run-queue behavior
that was dependent on linkage order (see the linked bug) when end_sema
and the pipe object were made non-static..
Adding a k_sem_init() call fixes the corrupt issue, but really the
right thing is to use the DEFINE macro, so do that instead. Note that
that the initializer changes the linkage order too (by putting the
semaphore in a separate segment), so... yeah, it's actually impossible
to prove that this patch in isolation resolves the issue seen without
manual validation.

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

Arguments are not needed and in some cases are being set as unused in
the same function. The test_main function is called from ztest main
routine without any arguments.

This will prepare test cases and samples with metadata and information
that will be consumed by the sanitycheck script which will be changed to
parse YAML files instead of ini.
