9342e3d32e doc: getting_started: Remove redundant and erronous doc's
The 'getting started' documentation is stating that one should set
some environment variables, but this is not necessary because the user
has already been instructed to set the variables in the
platform-specific guides.

The duplicated documentation should be removed because it is inferiour
to the original documentation. E.g. this documentation does not
describe how to permanently set environment variables. Also, it is
confusingly demonstrating how to use the SDK on Windows, but this is
not supported.

I believe that the purpose of the section is to verify that the user
has not misconfigured or misinstalled the toolchain, but this
responsibility is handled better by CMake itself.

b1e45b413e subsys: fs: Add Non Volatile Storage (NVS) for zephyr
Zephyr supports fatfs, nffs and fcb as storage layer. fatfs and nffs
are less suited for application in memory restricted IC's. fcb has a
smaller footprint but has a complex api.

The proposed module is a module with a even smaller footprint compared
to fcb and a simple interface for reading and writing entries. The
module provides wear levelling of flash. This allows the module to be
used not only to store configuration settings but to store device state
(e.g. state of a light switch over reboots) of a zephyr device.

Fixes buffer overflow by introducing maximum read length in nvs_read()
and nvs_read_hist().

Fixes nvs_write() not to reflash the same data. Allows the user to do
call nvs_write() for all defined entries without worries about flash
wear.

Fixes garbage collection error where wrong data could be copied.

Add nvs_delete() to allow deleting a stored entry. A deleted entry will
not be copied to a new flash sector

Include flash wear information in the README.md documentation

0/25 Update module after reviewers remarks, added documentation to
nvs.h, removed README.md by nvs.rst in doc/subsystems folder

04/26 Update module after reviewers remarks, updated nvs.rst, added more
documentation to samples/subsys/nvs/src/main.c, updated doxygen info
in nvs.h (hope this time it works).

04/26 Update subsystems.rst to include nvs.restart

04/27 Updated nvs.c and nvs.h to avoid a possible flash deletion loop
when the file system is full.

04/29 Updated nvs_write to detect and ignore deletes of non-existing
items

05/06 Update NVS module to return standard error codes, removed low
level API, added configuration options. NVS now uses the board dts to
determine the flash storage location (FLASH_AREA_STORAGE_OFFSET).

05/06 Update nvs.rst. Updated intendation and added intermediate
variables in nvs.c to make the code easier to read.

05/06 Update nvs.rst.

05/07 Update nvs.rst

05/08 Changed the API to a more standard file system API.

05/08 Removed cnt_max from nvs_read() as it is not used.

05/08 Removed #ifdef(CONFIG_NVS_LOG) from nvs_priv.h, now the module can
be build with debugging off.

05/09 Removed configuration options for SECTOR_SIZE, SECTOR_COUNT and
MAX_ELEM_SIZE. It is now easy to support multiple NVS filesystems on
one or multiple devices. Changed logging to support newlib systems.
Thanks to Olivier Martin for reporting and proposed changes.

486c5a54e5 doc: add doc writing guides w/common usages
I've collected some of the common issues encountered with doc reviews
into a new contributing document, and included use of the
Zephyr-specific extension for generating code building examples.

Updated conf.py and created an external list of substitutions making it
easier to manage them without editing the sphinx conf file (and
documented this).

Tweaked the comments in the application.py extension python code to
render better in the generated doc that extracts these comments (keeps
the documentation in the python code too to ease maintenance when
updates are made).

Updated the sample template to mention use of this sphinx extension.

18859171a3 doc: flatten doxygen-generated HTML structure
The current doxygen configuration settings create 4096 folders to hold
the generated HTML output (with names such as d3/ddb/).  This makes it
difficult to know what an URL would be for a particular module's
(defgroup's) documentation.  By not creating these subdirectories,
module documentation file names become quite predictable:

     group__<group name>.html

(e.g., group__sensor__interface.html) allowing us to create
links from the Sphinx-generated documentation into the doxygen-generated
HTML content (this part is under investigation).

d22b7c9f2d Bluetooth: Remove bt_storage API
The same functionality is now supported by the settings-based
solution, so remove bt_storage out of the way. There were stubs in
bt_storage to handle per-peer information (e.g. pairing keys) but this
was never actually implemented in full. The next step is to add this
support to the settings-based solution.

Leave the code for generating temporary IRK and identity address in
case BT_SETTINGS is not enabled. Also leave the code for using vendor
HCI to read the identity address, in which case the settings
implementation will not touch it.

Introduce a new bt_unpair() API to replace the removed
bt_storage_clear(), since the latter was actually doing more than just
storage management: it was also handling runtime storage of pairing
information. Later, the bt_unpair() implementation will be extended to
clear settings-based pairing storage.

There is one feature that the bt shell module looses: the ability to
give a specific identity address to the "init" command as a parameter.
We might look later in the future if this is really needed, and add a
separate API for this.

63cb2334f0 doc: Document Zephyr's Kconfig configuration scheme
In particular, try to demystify Kconfig.defconfig files, and provide
guidelines on whether configuration settings should go in
BOARD_defconfig or Kconfig.defconfig.

The board porting section seems to be the most relevant one here, so put
the documentation there, with some "see also" links from elsewhere.
Things could be reorganized later if needed.

Give a general overview of visible and invisible Kconfig symbols as
well, as that ties in with the configuration scheme.

This is reverse-engineering on my part. The configuration scheme doesn't
seem to be documented anywhere prior.

3f55dafebc kernel: Deprecate k_thread_cancel() API
The only difference between this call and k_thread_abort() (beyond
some minor performance deltas) is that "cancel" will act as a noop in
cases where the thread has begun execution and will return an error.
"Abort" always succeeds, of course.  That is inherently racy when used
as a "stop the thread" API: there's no way in general (or at all in
SMP situations) to know that you're calling this function "early
enough" to catch the thread before it starts.

Effectively, all k_thread_cancel() gives you that k_thread_abort()
doesn't is an indication about whether or not a thread has started.
There are many other ways to get that information that don't require
dangerous kernel APIs.

Deprecate this function.  Zephyr's own code never used it except for
its own unit test.

Remove the following section from the introduction as well, as I think
it might make people wonder how they can have an existing kernel
configuration when they haven't created one. The updated configuration
section (which the introduction now has a forward reference to)
clarifies the zephyr/.config bit anyway.

    If omitted, the application's existing kernel configuration option
    values are used; if no existing values are provided, the kernel's

b57ac8a2ff doc: improve Sphinx search results output
The search result from Sphinx displays raw ReST file snippets showing
the context of the search hit.  While we could generate text versions of
the ReST files just for the search results, it would potentially double
the time to generate docs (run once to generate txt files, run again to
generate HTML).

Instead, this patch does a poor man's cleanup of the ReST markup on the
fly when the search summary snippets are written out.  Not perfect, but
looks much better.

It does expose a problem that some of our ReST content is not actually
written out into a .rst file. Content that's dynamically generated by
extensions, such as the sample code from zephyr-app-commands, can
yield a search result hit, but there's no hits in the .rst file content
itself.

Line 552-558 are the modified lines from the Sphinx-provided
searchtools.js that does the pattern match/replace.

 - Defaults

 - Other symbols selecting or implying the symbol

The current symbol value and visibility are no longer displayed. They

The bottom of the reference page also includes the symbol represented in
Kconfig format (including propagated dependencies).

All references to defined symbols appearing in expressions are turned
into links, which can be clicked on to jump to the reference page for
that symbol.

The following (slightly outdated) screenshot gives an idea of the
