1e46bb3bb5 lib: os: ring_buffer: Allow using full buffer capacity
Previously, ring buffer had capacity of provided buffer size - 1. This
trick was used to distinguish between empty and full states. It had one
drawback: ring buffer could not be used as a pool of equal sized buffers
(using ring_buf_put_claim and ring_buf_get_claim).
Reworked internals to use non wrapping head and tail. Since they are
non wrapping, there is no issue with distinguishing between empty and
full. Since this appraoch would be vulnerable to wrapping on 32 bit
boundary, added a mechanism which periodically reduces all indexes to
avoid 32 bit wrapping.

After this rework, buffer has one byte more capacity. Simple test shows
slight performance improvement.

Updated tests to reflect increased capacity and added test to check if
it is possible to continuesly allocated 2 buffers of half ring buffer
size.

ad2fd44d7a Bluetooth: Mesh: Encapsulate feature config
Moves mesh feature configuration to a separate module, deprecating the
bt_mesh_cfg_srv structure. The initial values for the features should
now be enabled through KConfig, where new config entries have been added
for each feature.

This removes the upward dependency on the config server from the core
stack, and makes the config server a pure frontend for the configuration
states, as all spec mandated behavior around the feature states is now
encapsulated.

808dd9e684 doc: reference: add devicetree bindings content
Add generated documentation content for known devicetree bindings
using the Binding abstraction which was just added to edtlib. This
works similarly to the way Kconfig content is generated, so extract a
bit of common helper code for doing that out and rename the relevant
files to keep the distinction clear.

Make the documentation build system respect a preset DTS_ROOT. In this
way, out of tree bindings can be added to the generated content by
telling the documentation build system where to find them, identically
to how out of tree bindings can be added to a Zephyr application.

Similarly, make the output directory configurable.

4abc38b342 doc: usermode: stack access policy change
The current policy of always excluding stacks that aren't
owned by the current thread only works well on MPU systems,
where it is very fast to have a reserved MPU region corresponding
to the stack buffer of the current thread.

This unfortunately is not efficient on MMU-based systems, it
would require either a different set of page tables per thread
or an expensive page table update on context switch.

This PR relaxes the documented policy to leave it up to the
implementation whether threads that all belong to the same
memory domain can see each other's stacks.

There's lots of precedent for this, for example on Linux threads
in the same process can all access each other's stacks.

c1f6c7d19e doc: extract_content.py: support multiple build directories
Exclude (other) build directories with a CMakeCache.txt file as they
typically contain previous output from ourselves.

One key feature of 'out of source" builds offered by CMake is allowing
multiple build directories. For instance to build different
configurations without starting from scratch. Unfortunately, the
extract_content.py code had a severe issue with multiple build
directories with an interesting effect on build times, see simple
reproduction below:

cd doc/
cmake -B _build/
cmake -B _b2

 # Repeat these a couple times
make -C _build content
make -C _b2 content

find -name rst
./_b2/rst
./_b2/rst/doc/_build/rst

e3c50af3e6 doc: restore sphinx-html and sphinx-latex shortcuts
Fixes commit 15fbf707ca ("doc: revert to copy files with
extract_content.py directly") that removed (2 years ago!) the definition
of EXTRACT_CONTENT_OUTPUTS while leaving it in use by sphinx-html and
sphinx-latex.

On my Linux box "make sphinx-html" is more than 5 times faster than
"htmldocs", likely because it does not build doxygen nor kconfig.

Also add missing WORKING_DIRECTORY for consistency with regular
targets and to fix this error:

Exception occurred:
  File "~/.local/lib/python3.8/site-packages/sphinx/
                   search/__init__.py", line 284, in __init__
