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 rework commit 77b8f5c1f6
Comparing it to BT IPSP is a the wrong comparison: BT IPSP does specify
6lo/ipv6 for it to work. Whereas 802.15.4 does not.
Instead of selecting 6lo from 802.15.4's Kconfig, let's do the reverse
way. If the user enabled 802.15.4 and IPv6 as well (to which 6lo
depends on), then 6lo is enabled by default as using IPv6 on 15.4
without it does not make much sense.

If IEEE 802.15.4 reassembly function ieee802154_reassemble() returns
anything other than NET_CONTINUE, then drop that packet. Earlier
it only dropped the packet if NET_DROP was returned but the reassembly
might also return NET_OK. In that case the pkt is freed already and
pkt->frags pointer is NULL. This caused NULL pointer access in L2 when
packet was received.

802.15.4 IP-based networking requires 6LoWPAN layer and won't work
correctly without it. So, if NET_L2_IEEE802154 is select,

does (NET_L2_BT causes selection of NET_6LO).

This is useful to enable error/warning logging across the net
codebase (less useful for debug level logging, but that's true
for CONFIG_NET_LOG_GLOBAL already).
Implementation-wise, instead of keeping adding to long list of

inter-dependencies, add "default y if NET_LOG_GLOBAL" to
individual components' logging options.

prepare_arp() was unreferencing original pkt (called pending there) in
case of error.
net_prepare_arp() was always unreferencing pkt, though it could have
been already unreferenced by prepare_arp() as seen previously which is
an extra bogus unref in this case.
And in case it returned NULL, ethernet_send() would return NET_DROP
which in turn would make net_if's tx code to unref again the pkt.
This patch ensures pkt is unrefed only once and at the right place.

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.
