This commit fixes some edge cases when using net_bufs with reserved
bytes (headroom) as fragments of a net_pkt.
Signed-off-by: Reto Schneider <reto.schneider@husqvarnagroup.com>
When operating on a net_pkt using the cursor functionality, reserved
bytes (headroom) are currently not respected.
This commit adds test cases exposing this problem. Fix will be

Unit tests were failing to build because random header was included by
kernel_includes.h. The problem is that rand32.h includes a generated
file that is either not generated or not included when building unit
tests. Also, it is better to limit the scope of this file to where it is
used.

If we have removed first net_buf, then we must not restore the
original cursor as that will point to wrong head net_buf.
Add also unit test to check that the packets are removed
properly.

beginning of the function, also document that the cursor
is reset after this call.

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.

drivers to either set a proper PM function or, if not supported or PM

All existing macro calls are updated. Since no PM support was added so
far, device_pm_control_nop is used as the default everywhere.

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.

Some locations like DHCPv4 client create a prefilled packet by appending
new fragments in a loop with one byte each via net_pkt_append_u8() which
is wasteful and noisy. This patch adds the new functions
net_pkt_append_memset() which creates fragments as needed in the desired
size and initialises it to the specified value.
This change also adds a unittest for the new function.

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.
