Having posix headers in the default include path causes issues with the
posix port. Move to a sub-directory to avoid any conflicts.

Currently all posix APIs are put into single files (pthread.c).
This patch creates separate files for different API areas.

The linker was always picking a weak handler over the actual one.
The linker always searches for the first definition of any function
weak or otherwise. When it finds this function it just links and
skips traversing through the full list.
In the context of userspace, we create the _handlers_ for each system
call in the respective file. And these _handlers_ would get linked to
a table defined in syscalls_dispatch.c. If for instance that this
handler is not defined then we link to a default error handler.
In the build procedure we create a library file from the kernel folder.
When creating this library file, we need to make sure that the file
syscalls_dispatch.c is the last to get linked(i.e userspace.c).
Because the table inside syscalls_dispatch.c would need all the
correct _handler_ definitions. If this is not handled then the system
call layer will not function correctly because of the linker feature.

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
