Sweep the entire documentation again. Last done in commit
209e64d9edf (qapi: Refill doc comments to conform to current
conventions).
To check the generated documentation does not change, I compared the
generated HTML before and after this commit with "wdiff -3". Finds no
differences. Comparing with diff is not useful, as the reflown
paragraphs are visible there.

Use the no-option form of ".. qmp-example::" to convert any Examples
that do not have any form of caption or explanation whatsoever. Note
that in a few cases, example sections are split into two or more
separate example blocks. This is only done stylistically to create a
delineation between two or more logically independent examples.
See commit-3: "docs/qapidoc: create qmp-example directive", for a
detailed explanation of this custom directive syntax.
See commit+3: "qapi: remove "Example" doc section" for a detailed
explanation of why.
Note: an empty "TODO" line was added to announce-self to keep the
example from floating up into the body; this will be addressed more
rigorously in the new qapidoc generator.

Generally, surround command-line options with ``literal`` markup to help
it stand out from prose in rendered HTML, and add cross-references to
replace "see also" messages.
References to types, values, and other QAPI definitions are not yet
adjusted here; they will be converted en masse in a subsequent patch
after the new QAPI doc generator is merged.

We do not need a dedicated section for notes. By eliminating a specially
parsed section, these notes can be treated as normal rST paragraphs in
the new QMP reference manual, and can be placed and styled much more
flexibly.
Convert all existing "Note" and "Notes" sections to pure rST. As part of
the conversion, capitalize the first letter of each sentence and add
trailing punctuation where appropriate to ensure notes look sensible and
consistent in rendered HTML documentation. Markup is also re-aligned to
the de-facto standard of 3 spaces for directives.
Update docs/devel/qapi-code-gen.rst to reflect the new paradigm, and
update the QAPI parser to prohibit "Note" sections while suggesting a
new syntax. The exact formatting to use is a matter of taste, but a good
candidate is simply:
.. note:: lorem ipsum ...
... dolor sit amet ...
... consectetur adipiscing elit ...
... but there are other choices, too. The Sphinx readthedocs theme
offers theming for the following forms (capitalization unimportant); all
are adorned with a (!) symbol () in the title bar for rendered HTML
docs.
See
https://sphinx-rtd-theme.readthedocs.io/en/stable/demo/demo.html#admonitions
for examples of each directive/admonition in use.
These are rendered in orange:
.. Attention:: ...
.. Caution:: ...
.. WARNING:: ...
These are rendered in red:
.. DANGER:: ...
.. Error:: ...
These are rendered in green:
.. Hint:: ...
.. Important:: ...
.. Tip:: ...
These are rendered in blue:
.. Note:: ...
.. admonition:: custom title
admonition body text
This patch uses ".. note::" almost everywhere, with just two "caution"
directives. Several instances of "Notes:" have been converted to
merely ".. note::", or multiple ".. note::" where appropriate.
".. admonition:: notes" is used in a few places where we had an
ordered list of multiple notes that would not make sense as
standalone/separate admonitions. Two "Note:" following "Example:"
have been turned into ordinary paragraphs within the example.
NOTE: Because qapidoc.py does not attempt to preserve source ordering of
sections, the conversion of Notes from a "tagged section" to an
"untagged section" means that rendering order for some notes *may
change* as a result of this patch. The forthcoming qapidoc.py rewrite
strictly preserves source ordering in the rendered documentation, so
this issue will be rectified in the new generator.

The new QMP documentation generator wants to parse all examples as
"QMP". We have an existing QMP lexer in docs/sphinx/qmp_lexer.py (Seen
in-use here: https://qemu-project.gitlab.io/qemu/interop/bitmaps.html)
that allows the use of "->", "<-" and "..." tokens to denote QMP
protocol flow with elisions, but otherwise defers to the JSON lexer.
To utilize this lexer for the existing QAPI documentation, we need them
to conform to a standard so that they lex and render correctly. Once the
QMP lexer is active for examples, errant QMP/JSON will produce warning
messages and fail the build.
Fix any invalid JSON found in QAPI documentation (identified by
attempting to lex all examples as QMP; see subsequent
commits). Additionally, elisions must be standardized for the QMP lexer;
they must be represented as the value "...", so three examples have been
adjusted to support that format here.

Convert the qmp-spec.txt document to restructuredText.
Notable points about the conversion:
* numbers at the start of section headings are removed, to match
the style of the rest of the manual
* cross-references to other sections or documents are hyperlinked
* various formatting tweaks (notably the examples, which need the
-> and <- prefixed so the QMP code-block lexer will accept them)
* English prose fixed in a few places

rST parses something like
first line
second line
as a definition list item, where "first line" is the term being
defined by "second line".
This bites us in a couple of places. Here's one:
# @bps_max: total throughput limit during bursts,
# in bytes (Since 1.7)
scripts/qapi/parser.py parses this into an "argument section" with
name "bps_max" and text
total throughput limit during bursts,
in bytes (Since 1.7)
docs/sphinx/qapidoc.py duly passes the text to the rST parser, which
parses it as another definition list. Comes out as nested
definitions: term "bps_max: int (optional)" defined as term "total
throughput limit during bursts," defined as "in bytes (Since 1.7)".
rST truly is the Perl of ASCII-based markups.
Fix by deleting the extra indentation.

Perfectly aligned things look pretty, but keeping them that
way as the schema evolves requires churn, and in some cases
newly-added lines are not aligned properly.
Overall, trying to align things is just not worth the trouble.

In commit 26ec4e53f2 and similar commits we fixed the indentation
for doc comments in our qapi json files to follow a new stricter
standard for indentation, which permits only:
@arg: description line 1
description line 2
or:
@arg:
line 1
line 2
Unfortunately since we didn't manage to get the script changes that
enforced the new style in, a variety of commits (eg df4097aeaf71,
2e4457032105) introduced new doc text which doesn't follow the new
stricter rules for indentation on multi-line doc comments. Bring
those into line with the new rules.

The various schemas included in QEMU use a JSON-based format which
is, however, strictly speaking not valid JSON.
As a consequence, when vim tries to apply syntax highlight rules
for JSON (as guessed from the file name), the result is an unreadable
mess which mostly consist of red markers pointing out supposed errors
in, well, pretty much everything.
Using Python syntax highlighting produces much better results, and
in fact these files already start with specially-formatted comments
that instruct Emacs to process them as if they were Python files.
This commit adds the equivalent special comments for vim.

Add feature 'deprecated' to the deprecated QMP commands, so their
deprecation becomes visible in output of query-qmp-schema. Looks like
this:
{"name": "query-cpus",
"ret-type": "[164]",
"meta-type": "command",
"arg-type": "0",
---> "features": ["deprecated"]}
Management applications could conceivably use this for static
checking.
The deprecated commands are change, cpu-add, migrate-set-cache-size,
migrate_set_downtime, migrate_set_speed, query-cpus, query-events,
query-migrate-cache-size.
The deprecated command arguments are block-commit arguments @base and
@top, and block_set_io_throttle, blockdev-change-medium,
blockdev-close-tray, blockdev-open-tray, eject argument @device.
The deprecated command results are query-cpus-fast result @arch,
query-block result @dirty-bitmaps, query-named-block-nodes result
@encryption_key_missing and result @dirty-bitmaps's member @status.
Same for query-block result @inserted, which mirrors
query-named-block-nodes.

This adds a new QAPI-based monitor_init() function. The existing
monitor_init_opts() is rewritten to simply put its QemuOpts parameter
into a visitor and pass the resulting QAPI object to monitor_init().
This will cause some change in those error messages for the monitor
options in the system emulator that are now generated by the visitor
rather than explicitly checked in monitor_init_opts().

misc.json contains definitions that are related to the system emulator,
so it can't be used for other tools like the storage daemon. This patch
moves basic functionality that is shared between all tools (and mostly
related to the monitor itself) into a new control.json, which could be
used in tools as well.
