There are 174 RX/TX net pkt reserved, this make build fail
with some boards due to ram overflow (e.g quark_se_c1000).
Fix this by reducing NET_PKT RX/TX reserve to 100, which
seems fair enough for this use case. Moreover, don't think
there is any reason to have more NET_PKT than NET_BUF.

Right now in FIN_WAIT1 state, if we receive FIN+ACK message, then
tcp state changed to FIN_WAIT2 on ACK flag and immediately on FIN
flag state changed to TIME_WAIT. Then final ACK is prepared and sent
(in queue at-least) to peer. Again immediately state changed to
TCP_CLOSED, where context is freed. net_context_put frees context
and releases tcp connection. Final ACK packet which is in queue
is dropped.
As a side effect of freed ACK packet, peer device keep on sending
FIN+ACK messages (that's why we see a lot of "TCP spurious
retransimission" messages in wireshark). As a result
of context free (respective connection handler also removed), we see
lot of packets dropped at connection input handler and replying with
ICMP error messages (destination unreachable).
To fix this issue, timewait timer support is required. When tcp
connection state changed to TIMEWAIT state, it should wait until
TIMEWAIT_TIMETOUT before changing state to TCP_CLOSED. It's
appropriate to close the tcp connection after timewait timer expiry.
Note: Right now timeout value is constant (250ms). But it should
be 2 * MSL (Maximum segment lifetime).

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

When an app uses a construct such as:
obj-y = main.o ../../../../samples/bluetooth/gatt/hrs.o
in its makefile, it causes said object module to be built in the
source tree, not in the object tree.
When building massively parallel, this usually resuls on the files
getting corrupted, leading to bugs such as:
https://jira.zephyrproject.org/browse/ZEP-2316https://jira.zephyrproject.org/browse/ZEP-2317
src/../../../../samples/bluetooth/gatt/.gap.o.cmd:3: warning: NUL character seen; rest of line ignored
src/../../../../samples/bluetooth/gatt/.gap.o.cmd:4: warning: NUL character seen; rest of line ignored
src/../../../../samples/bluetooth/gatt/.gap.o.cmd:5: *** missing separator. Stop.
as multiple build are trying to touch the same file in the source tree
and of course, race and causes a build bug.
We have known about this issue for a long time, but it requires
modifications in the build system that there is no time to tackle.
A suggested workaround is to include the source files into a local .c
file, so this is what this patch does, to remove the random noise.

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.

For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.
There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:
samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c
Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

- 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.
