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.

Adapt the MyNewt non-volatile configuration system to become a settings
system in Zephyr.
The original code was modifed in the following ways:
* Renamed from config to settings
* Use the zephyr FCB, FS API, and base64 subsystems
* lltoa like function was added to sources as it was required but not
included in Zephyr itself.
* The original code was modified to use Zephyr's slist.h as single
linked list implementation.
* Reworked code which was using strtok_r, added function
for decoding a string to a s64_t value.
* Thank to the above the settings subsys doesn't require newlibc anymore.
