qapi: remove "Example" doc section

Fully eliminate the "Example" sections in QAPI doc blocks now that they
have all been converted to arbitrary rST syntax using the
".. qmp-example::" directive. Update tests to match.

Migrating to the new syntax
---------------------------

The old "Example:" or "Examples:" section syntax is now caught as an
error, but "Example::" is stil permitted as explicit rST syntax for an
un-lexed, generic preformatted text block.

('Example' is not special in this case, any sentence that ends with "::"
will start an indented code block in rST.)

Arbitrary rST for Examples is now possible, but it's strongly
recommended that documentation authors use the ".. qmp-example::"
directive for consistent visual formatting in rendered HTML docs. The
":title:" directive option may be used to add extra information into the
title bar for the example. The ":annotated:" option can be used to write
arbitrary rST instead, with nested "::" blocks applying QMP formatting
where desired.

Other choices available are ".. code-block:: QMP" which will not create
an "Example:" box, or the short-form "::" code-block syntax which will
not apply QMP highlighting when used outside of the qmp-example
directive.

Why?
----

This patch has several benefits:

1. Example sections can now be written more arbitrarily, mixing
explanatory paragraphs and code blocks however desired.

2. Example sections can now use fully arbitrary rST.

3. All code blocks are now lexed and validated as QMP; increasing
usability of the docs and ensuring validity of example snippets.

(To some extent - This patch only gaurantees it lexes correctly, not
that it's valid under the JSON or QMP grammars. It will catch most
small mistakes, however.)

4. Each qmp-example can be titled or annotated independently without
bypassing the QMP lexer/validator.

(i.e. code blocks are now for *code* only, so we don't have to
sacrifice exposition for having lexically valid examples.)

NOTE: As with the "Notes" conversion (d461c279737), this patch (and the
three preceding) may change the rendering order for Examples in
the current generator. The forthcoming qapidoc rewrite will fix
this by always generating documentation in source order.

qapi: convert "Note" sections to plain rST

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.

qapi/parser: preserve indentation in QAPIDoc sections

Change get_doc_indented() to preserve indentation on all subsequent text
lines, and create a compatibility dedent() function for qapidoc.py that
removes indentation the same way get_doc_indented() did.

This is being done for the benefit of a new qapidoc generator which
requires that indentation in argument and features sections are
preserved.

Prior to this patch, a section like this:

```
@name: lorem ipsum
dolor sit amet
consectetur adipiscing elit
```

would have its body text be parsed into:

```
lorem ipsum
dolor sit amet
consectetur adipiscing elit
```

We want to preserve the indentation for even the first body line so that
the entire block can be parsed directly as rST. This patch would now
parse that segment into:

```
lorem ipsum
dolor sit amet
consectetur adipiscing elit
```

This is helpful for formatting arguments and features as field lists in
rST, where the new generator will format this information as:

```
:arg type name: lorem ipsum
dolor sit amet
consectetur apidiscing elit
```

...and can be formed by the simple concatenation of the field list
construct and the body text. The indents help preserve the continuation
of a block-level element, and further allow the use of additional rST
block-level constructs such as code blocks, lists, and other such
markup.

This understandably breaks the existing qapidoc.py; so a new function is
added there to dedent the text for compatibility. Once the new generator
is merged, this function will not be needed any longer and can be
dropped.

I verified this patch changes absolutely nothing by comparing the
md5sums of the QMP ref html pages both before and after the change, so
it's certified inert. QAPI test output has been updated to reflect the
new strategy of preserving indents for rST.

In particul

qapi/parser: demote QAPIExpression to Dict[str, Any]

Dict[str, object] is a stricter type, but with the way that code is
currently arranged, it is infeasible to enforce this strictness.

In particular, although expr.py's entire raison d'être is normalization
and type-checking of QAPI Expressions, that type information is not
"remembered" in any meaningful way by mypy because each individual
expression is not downcast to a specific expression type that holds all
the details of each expression's unique form.

As a result, all of the code in schema.py that deals with actually
creating type-safe specialized structures has no guarantee (myopically)
that the data it is being passed is correct.

There are two ways to solve this:

(1) Re-assert that the incoming data is in the shape we expect it to be, or
(2) Disable type checking for this data.

(1) is appealing to my sense of strictness, but I gotta concede that it
is asinine to re-check the shape of a QAPIExpression in schema.py when
expr.py has just completed that work at length. The duplication of code
and the nightmare thought of needing to update both locations if and
when we change the shape of these structures makes me extremely
reluctant to go down this route.

(2) allows us the chance to miss updating types in the case that types
are updated in expr.py, but it *is* an awful lot simpler and,
importantly, gets us closer to type checking schema.py *at
all*. Something is better than nothing, I'd argue.

So, do the simpler dumber thing and worry about future strictness
improvements later.

qapi: New documentation section tag "Errors"

We use section "Returns" for documenting both success and error
response of commands.

I intend to generate better command success response documentation.
Easier when "Returns" documents just he success response.

Create new section tag "Errors". The next two commits will move error
response documentation from "Returns" sections to "Errors" sections.

qapi: Divorce QAPIDoc from QAPIParseError

QAPIDoc stores a reference to QAPIParser just to pass it to
QAPIParseError. The resulting error position depends on the state of
the parser. It happens to be the current comment line. Servicable,
but action at a distance.

The commit before previous moved most uses of QAPIParseError from
QAPIDoc to QAPIParser. There are just three left. Convert them to
QAPISemError. This involves passing info to a few methods. Then drop
the reference to QAPIParser.

The three errors lose the column number. Not really interesting here:
it's the comment line's indentation.

qapi: Reject multiple and empty feature descriptions

The parser recognizes only the first "Features:" line. Any subsequent
ones are treated as ordinary text, as visible in test case
doc-duplicate-features. Recognize "Features:" lines anywhere. A
second one is an error.

A 'Features:' line without any features is useless, but not an error.
Make it an error. This makes detecting a second "Features:" line
easier.

qapi/run-state.json actually has an instance of this since commit
fe17522d854 (qapi: Remove deprecated 'singlestep' member of
StatusInfo). Clean it up.

qapi: Rewrite doc comment parser

QAPISchemaParser is a conventional recursive descent parser. Except
QAPISchemaParser.get_doc() delegates most of the doc comment parsing
work to a state machine in QAPIDoc. The state machine doesn't get
tokens like a recursive descent parser, it is fed tokens.

I find this state machine rather opaque and hard to maintain.

Replace it by a conventional parser, all in QAPISchemaParser. Less
code, and (at least in my opinion) easier to understand.
