Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Move test related code and the testsuite away from tests/ and make it a
proper subsystem.
The way tests were integrate in the tree was not obvious and actual
tests were intermixed with the testsuite code.
This will allow us to have trees with the testcode and without the
samples by just remove the folders tests/ and samples, needed for
isolating actual code from test/sample code.

lib/ was starting to get messy and inconsitent. Files being either
dumped in the root or in sub-directories without a clear plan.
Move all library components into one single folder and call it 'os'.

Used as a checksum on command messages when talking with MMC cards.
Implemented using the unwound bytewise implementation from
https://en.wikipedia.org/wiki/Computation_of_cyclic_redundancy_checks
which is a good mix of size and speed.
The API and naming matches lib/crc7.c in Linux.

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.

Adding a new kernel object type or driver subsystem requires changes
in various different places. This patch makes it easier to create
those devices by generating as much as possible in compile time.
No behavior change.

The existing version of crc16_ccitt() is actually CRC-16/AUG-CCITT and
gives different results to Linux, Contiki, and the CRC unit in the
SAM0 SOC. This version matches Linux.
Note that this is an incompatible API change.
