Andrei Emeltchenko e408d9c3a4 doc: usb: Use new USB API for sample code
Replace sample code, making it use newest USB API, reading code
directly from sources, and changing to the simplest sample - loopback.
CDC ACM is quite big and modifying sample would render line change

Marti Bolivar 23d12e9e68 doc: reorder the sections for better flow
Put the Developer Guides after the Getting Started guide, and make
sure the Application Development Primer is the first item in the
Developer Guides. Make some other ordering adjustments as well.

These changes collectively make for a more logical order for linearly
reading through the Zephyr documentation for the average user.
"Average user" here is defined as a person who wants to:

1. learn what Zephyr is and its distinguishing features
2. install a Zephyr development environment, building/running hello
   world
3. learn the basics of how Zephyr applications are structured
4. start diving deeper

This privileges "users" over "developers", i.e. it pushes sections
related to Zephyr's internals and how to edit them down lower in the
order.

Marti Bolivar 0d811b9aee doc: overhaul getting_started
The getting started documentation has become a bit of a mess over
time:

- The reader needs to jump forward and backward in the documents
  depending on what their system already has installed (e.g. "start by
  cloning Zephyr, oh wait, see below if you don't have Git yet" etc.).

- The operating system setup guides, toolchain setup instructions, and
  application build and run information have each become their own
  balkanized fiefdom, with duplicated, confusing and sometimes
  inconsistent results.

- Linux documentation for all distributions is incomplete in some
  places (the Arch documentation in particular is vestigial)
  and wrong in others (platforms like Ubuntu still nominally require
  tools, like autoconf, that haven't been necessary since we stopped
  using the C Kconfig tools)

- The dependencies needed to build the documentation have
  gotten *huge* since the LaTeX additions and massively overstate the
  footprint of Zephyr's real dependencies. This is particularly a
  problem on Linux, where those dependencies were not clearly
  separated from those needed to build Zephyr.

- The toolchain setup documentation is confusing and scattered across
  the main file and the platform-specific files. There are various
  bits of incomplete and/or incorrect information. For example, the
  docs imply that you can use the Zephyr SDK on non-Linux hosts, which
  isn't true. As another example, some toolchains, such as GNU Arm
  Embedded, are documented several times. As a final example, some
  toolchains, such as Intel's ISSM, are squirrelled away in the
  Windows document when there are Linux builds available.

Overhaul the pages to fix these issues and otherwise clean up the
language. One significant side-effect is that all the
toolchain-related information is rooted in a single toctree. Another
is that it should now be possible to follow the instructions, in
order, on any supported platform.

Marti Bolivar d7dc113783 doc: avoid copying content twice
In a clean build, Ninja is creating copies of the extracted
documentation outputs regardless of whether they already exist or
not. I can't explain this behavior from the documentation of the build
command, but it's so, even if extract_content.py is patched to use
copyfile() instead of copy2() so that outputs (copied .rst files in
the build directory) have strictly newer mtimes than inputs (source
tree .rst files).

This extra copying doesn't happen for incremental builds, for some
reason.

To account for this behavior, add and use an extract_content.py option
that skips content extraction completely and leaves that all up to the
add_custom_command() which tracks each individual input->output build
command.

Marti Bolivar d9f512cbcf doc: add sphinx-html and sphinx-latex convenience targets
Most of time (i.e. when just writing to .rst files or editing images,
rather than editing Doxygen or Kconfig), a full rebuild of the docs
pipeline is not necessary.

This is unfortunate, because it takes over a minute to re-run doxygen
etc. (on my system), whereas an incremental sphinx-build run should
only take a few seconds.

As a band-aid to help developers who have already generated a docs
build and know the consequences of their actions, add "sphinx-html"
and "sphinx-latex" targets. These just re-extract content files into
the build directory and run sphinx-build. This makes for much faster
documentation edit/compile/read loops.

Add some extra COMMENTs while we're here, to make it more obvious
what's going on when the docs build system crunches on something.

A "proper" solution for changing "ninja html" to have similar
performance would need, at least, to:

- only re-run doxygen if any source files have changed
- only re-generate Kconfig if any of those files have changed

That's all left to future work, as this is good enough to make
rebuilding the docs bearable for me.

Marti Bolivar 0913c296cf doc: fix extract_content.py dependency tracking
The logic which copies source documentation files into the build
directory could use some improvements to its dependency management, so
that when a source file changes, extract_content.py gets re-run.

Make these changes as follows:

- Add an --outputs flag to extract_content.py, so that the
  sources it depends on and generates can be saved into a file and
  thus made known to the build system

- Change the way the sources and destination are specified in the
  extract_content.py command line so that the entire job can be done
  in a single command, rather than multiple (to avoid having to
  collate multiple --outputs files in CMake)

- Extract the content at configure time with execute_process(),
  tracking all inputs and outputs within the build system itself. Use
  this information to make sure that each individual output depends on
  just its exact input file, ensuring updated inputs produce updated
  outputs without having to call extract_content.py again.

- Ensure that the "content" build system target depends on all the
  outputs, transitively triggering a rebuild any time an input
  file (e.g. .rst documentation file or included image/source file)
  changes.

Marti Bolivar 9802f883f5 doc: rewrite extract_content.py for better input/output tracking
Separate the phases of creating the list of outputs (and output
directories) from the actual creation of these outputs. This lays the
groundwork for just printing the inputs and outputs in a subsequent
patch, enabling CMake to track dependencies properly.

In the now-separate output generation phase, use shutil.copy2() to
preserve metadata like access and modification times when possible,
rather than re-reading every file and seeing if the contents are
different. This has the same semantics but is clearer and potentially
more efficient, as the initial copies have more accurate relative
timestamps.

Ulf Magnusson 92ef8582b9 Kconfig: Remove redundant $(ZEPHYR_BASE) from 'source's
The $srctree environment variable gives the path relative to which
'(o)source' statements work (the current directory is used if $srctree
is unset). It is set to $ZEPHYR_BASE in cmake/kconfig.cmake, so there's
no need to qualify the source of Kconfig.zephyr in sample Kconfig files
(or in external projects).

All 'source's in Zephyr assume that the Zephyr root directory is used as
the srctree as well, and would break otherwise.

Remove the $(ZEPHYR_BASE)s to make it clearer that all 'source'
statements work relative to the Zephyr root. There was some user
confusion on IRC.

Also explain how things work in the documentation.

Ulf Magnusson 5cfe06b6bc genrest/menuconfig: Fix crash for promptless choices
Update menuconfig (and Kconfiglib, just to sync) to upstream revision
256e5b3e38e92 to get the fix below in, for an issue in an external
project. Also update genrest.py with a similar fix (the genrest issue
was what originally prompted it).

    menuconfig: Improve/fix promptless choice handling

    The code assumed that all parent (interface) menus always have a
    prompt, which is false for items in promptless choices. This led to
    a crash e.g. when viewing the symbol information for a symbol within
    a promptless choice.

    Promptless choices with children can show up "legitimately" when
    people define choices in multiple locations to add symbols, though
    this is broken in the C tools.

    Use standard_sc_expr_str(node.item) instead of the non-existing
    prompt for promptless choices. That way they show up as
    '<choice (name if any>)>', which is consistent with how they're
    shown elsewhere.

    This commit also changes how choice names are displayed in
    show-name/show-all mode, to the standard_sc_expr_str() format.

Marti Bolivar 55b462cdfa scripts: update west to latest upstream version.
Update to the latest west. This includes a new 'attach' command. There
are also multi-repo commands, but those won't get exposed to the user
unless they install Zephyr using "west init" + "west fetch" (and not,
say, "git clone").

Replace the launchers; they now detect whether zephyr is part of a
multi-repo installation, and run the west code in its own repository
if that is the case.

This also requires an update to:

- the flash/debug CMakeLists.txt, as the new west package is no longer
  executable as a module and must have its main script run by the
  interpreter instead.

- the documentation, to reflect a rename and with a hack to fix
