Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

Switch to `NET_SOCKET_REGISTER` mechanism over the offloaded API
registration.
Including the following fixes from the review:
* The fd returned by the socket accept call needs to be finalized,
similar to how it is done for socket creation.
* sl_RecvFrom() in TI SimpleLink Host driver does not support NULL
pointers for 'from' address and address length, and sl_SendTo() does
not ignore the destination address when in connection mode, so passing
NULL would cause a failure. These issues have been reported to TI
(CC3X20SDK-1970, CC3X20SDK-1971).
Let's use sl_Recv and sl_Send to implement recvfrom/sendto in the case
of NULL addresses.
* simplelink_poll() should not process negative file descriptors in the
fds array after sl_Selecti() returns. A negative fd value indicates
that the entry is invalid and should be ignored.

With CONFIG_POSIX_API enabled, these samples now build under Zephyr
with exactly the same source as e.g. Linux (or in general, other POSIX
systems). However, building without CONFIG_POSIX_API (i.e. with
CONFIG_NET_SOCKETS_POSIX_NAMES aux option) is retained for now.
Add testcase definitions to build these samples with CONFIG_POSIX_API
in CI.

When using an IDE (e.g. Eclipse, Qt Creator), the project name gets
displayed. This greatly simplifies the navigation between projects when
having many of them open at the same time. Naming every project "NONE"
defeats this functionality.
This patch tries to use sensible project names while not duplicating
too much of what is already represented in the path. This is done by
using the name of the directory the relevant CMakeLists.txt file is
stored in. To ensure unique project names in the samples (and again, in
the tests folder) folder, small manual adjustments have been done.

Prepend the text 'cmake_minimum_required(VERSION 3.8.2)' into the
application and test build scripts.
Modern versions of CMake will spam users with a deprecation warning
when the toplevel CMakeLists.txt does not specify a CMake
version. This is documented in bug #8355.
To resolve this we include a cmake_minimum_required() line into the
toplevel build scripts. Additionally, cmake_minimum_required is
invoked from within boilerplate.cmake. The highest version will be
enforced.
This patch allows us to afterwards change CMake policy CMP000 from OLD
to NEW which in turn finally rids us of the verbose warning.
The extra boilerplate is considered more acceptable than the verbosity
of the CMP0000 policy.

With 323e8cf069 applied and printf() working out of the box,
CONFIG_NET_BUF_LOG=y workarounds can be removed from configs of
all samples.
Also, print an intro message at the start of each server sample,
to give a user hint that the app didn't just hang and what to do
next. (The port waiting for connection is printed. We can't (easily)
print host address, because the samples should run on both Zephyr
and POSIX systems, and finding out local host address would require
hairy #ifdef's undermining the purpose of these samples (that is,
showing that the *same* code can be used on both types of systems)).

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

this also makes the names shorter. It is also in line with what Linux

in order to be consistent, such as NET_L2_BLUETOOTH.

In many networking tests we had to configure SLIP in the prj.conf
leaving those configurations Qemu specific. This change enables SLIP for
QEMU targets automatically and allows reuse of prj.conf for multiple

Additionally, the TUN options is removed. This option was not used

To enable self-contained networking tests that do not depend on SLIP, we
