This includes:
* KConfig options for all lvgl options
* Kernel & user space memory management
* Zephyr to lvgl FS call mapping
* Color space conversion function

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Also simplify the default on STDOUT_CONSOLE. Defaults can be arbitrary
expressions, not just fixed values.

'default N' should have been 'default n', though they happen to have the
same effect here, due to undefined Kconfig symbols ('N') evaluating to
'n' in a boolean sense.
Kconfig bool symbols implicitly default to 'n', so remove the default
rather than fixing it.

Move posix layer from 'kernel' to 'lib' folder as it is not
a core kernel feature.
Fixed posix header file dependencies as part of the move and
also removed NEWLIBC related macros from posix headers.

Since base64 is such a simple and commonly used feature it makes no
sense to build the whole of mbedTLS for it. Instead take the
implementation that comes with mbedTLS and import it as a native library
outside of ext/ for all to use directly.

* ring_bufffer is in lib, so move the Kconfig out of the kernel.
* move one Kconfig used for json to lib/Kconfig alongside other
Kconfigs.

This is a minimal JSON parser (and string encoder helper). This has
been originally written for the NATS client sample project, but since
it's a generic bit of code, it's also being provided as a library
outside the NATS application source.
It's limited (no support for arrays, nested objects, only integer
numbers, etc), but it is sufficient for the NATS protocol to work.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Moved all libc Kconfigs to where the code is and remove the default
Kconfig for selecting the minimal libc. Minimal libc is now the default
if nothing else is configured in.
Removed the options for extended libc, this obviously was restricting
features in the minimal libc without a good reason, most of the
functions are available directly when using newlib, so there is no
reason why we need to restrict those in minimal libc.

This is a CoAP implementation tailored for Zephyr's requirements, it
tries to use memory predictably by exposing its control structures to
the user (so the user only pays for the features that are used) and
having a lightweight packet representation (the trade-off is that
adding options is not as efficient as it could be, if there were more
information available).

tinycrypt was built using the lib- scripts without any real benefit. We
also had a wrong placement of the Kconfig files under misc/ and a Kconfig
file for Crypto that was never used before.
