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.

Instead of always allocating both IPv6 and IPv4 address information
to every network interface, allow more fine grained address
configuration. So it is possible to have IPv6 or IPv4 only network
interfaces.
This commit introduces two new config options:
CONFIG_NET_IF_MAX_IPV4_COUNT and CONFIG_NET_IF_MAX_IPV6_COUNT
which tell how many IP address information structs are allocated
statically. At runtime when network interface is setup, it is then
possible to attach this IP address info struct to a specific
network interface. This can save considerable amount of memory
as the IP address information struct can be quite large (depends
on how many IP addresses user configures in the system).
Note that the value of CONFIG_NET_IF_MAX_IPV4_COUNT and
CONFIG_NET_IF_MAX_IPV6_COUNT should reflect the estimated number of
network interfaces in the system. So if if CONFIG_NET_IF_MAX_IPV6_COUNT
is set to 1 and there are two network interfaces that need IPv6
addresses, then the system will not be able to setup IPv6 addresses to
the second network interface in this case. This scenario might be
just fine if the second network interface is IPv4 only. The net_if.c
will print a warning during startup if mismatch about the counts and
the actual number of network interface is detected.

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

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
boards.
Additionally, the TUN options is removed. This option was not used
anywhere.
To enable self-contained networking tests that do not depend on SLIP, we
introduce the new option NET_TEST which disables TAP and allows testing
in QEMU without the need for a host interface.

- network packet data is still managed through net_buf, mostly named

- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
memory when TCP is enabled.

There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.
Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).
Though net_pkt if the new name, it still inherit its logic from net_buf.

This patch is the first of a serie that will separate completely net_pkt
from net_buf.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.
