Vinicius May f6ecf80ebb Documentation: brand new layout for NuttX documentation.

The documentation grew one page at a time, so the tree follows the
history of who wrote what and not the shape of NuttX. Scheduling is
spread over three places, a driver page can sit above the subsystem
that owns it, and the front page lists everything at the same level.
That is a lot to face when all you want to know is where the scheduler
lives.

This change files every page under the code it describes. It is a move,
not a rewrite: outside the ten pages named below, every page keeps the
text that is already in master, and no page's text is deleted.

What it does:

* Groups the table of contents into nine chapters.
* Moves the OS subsystems under os/: scheduling, memory, drivers,
  filesystem, networking, IPC, interrupts, libs, time.
* Renames the platform pages to the names the source tree uses, and
  derives their tags from the tree instead of by hand.
* Splits guides/ by subject.
* Adds Documentation/redirects.py, with a rule for every page that left
  its old path, so old URLs keep working. The redirect page also carries
  a link's #anchor across to the new page.

Ten pages have text that is new or rewritten. Nine of them are the
landing page of a chapter, which has to exist for the new structure:

    index                  the front page
    os/index               OS Design
    os/scheduling/index    Scheduling
    os/interrupts/index    Interrupts
    os/ipc/index           IPC
    os/time/index          Time and timers
    about/index            About
    developing/index       Developing NuttX
    ReleaseNotes/index     Release notes

The tenth is os/libs/libbuiltin, the only page here with technical
content: libs/libbuiltin/ had no page at all. Five SVG diagrams come
with these pages, hand-written XML with no editor metadata.

Nothing outside Documentation/ is touched.

How it was checked:

* Sphinx builds with -W: no warnings, and no document left outside a
  toctree.
* A script, offered in the PR, proves the narrow claim this rests on.
  For every page outside the ten named above it erases what a move
  touches -- link target, path, tag line, toctree block, table border --
  from the whole old text and the whole new text, and requires the two
  to be byte for byte identical. It also requires every sentence of a
  deleted page to turn up somewhere, and every page that left its old
  path to have a redirect, from a URL that existed, to where its content
  went. It exits non-zero and names the page if any of that is not true,
  and it tests added pages too, so forgetting to declare one cannot make
  it pass.
* An independent audit checked 133 factual claims on these ten pages
  against the tree, one shell command per claim: 130 confirmed, 1
  refuted and fixed here, 2 not checkable.
* tools/checkpatch.sh is clean over the range.

The diff is large because moving a page changes every link that points
to it. Most of it is pure renames, and board pages that gained one tag
line.

#10605 Implement ticket spinlock

A proposal to slove #1488

Implement ticket spinlock.

#10861 spinlock: Add spin_lock_init and spin_is_locked macro

align with Linux api naming.

#11102 sched: explicitly select the cpuload clock source configuration

Different configurations require different dependencies. Explicitly select dependencies to avoid automatically selecting inappropriate configurations.

#11334 stm32h7_adc: Dynamically set clock prescaler and BOOST

First commit is aligning naming and is a breaking change.

#10827 Improve adjtime() functionality

Prior pull request #9084 and issue #8858 added basic adjtime() support for the SAMv7 platform.

This pull request adds support for STM32 platform.

In addition I have made a few changes to the adjtime() configuration options:

Previously adjustments less than 1 microsecond per tick would be completely ignored. Now they are applied over a shorter period at a rate of 1 us per tick.
Previously CLOCK_ADJTIME_PERIOD was in units of 1/100th of second. Change to milliseconds to be more generally useful unit. Change setting name to CLOCK_ADJTIME_PERIOD_MS to make the unit change easier to notice.
Previously CLOCK_ADJTIME_SLEWLIMIT was in percentage. Most clock crystals have better accuracy than 1%, so the minimum slew rate was excessive. Change to CLOCK_ADJTIME_SLEWLIMIT_PPM with setting value in parts per million.
No need to use floating point math in clock_adjtime.c.

Impact

Users who have used CLOCK_ADJTIME_PERIOD and CLOCK_ADJTIME_SLEWLIMIT settings should update their configuration. New CLOCK_ADJTIME_PERIOD_MS is 10x the old period value, and new CLOCK_ADJTIME_SLEWLIMIT_PPM is 10000 times the old slewlimit.
