Add a new directive that marks the beginning of a QAPI "namespace", for
example; "QMP", "QGA" or "QSD". This directive will associate all
subsequent QAPI directives in a document with the specified
namespace. This does not change the visual display of any of the
definitions or index entries, but does change the "Fully Qualified Name"
inside the QAPI domain's object table. This allows for two different
"namespaces" to define entities with otherwise identical names -- which
will come in handy for documenting both QEMU QMP and the QEMU Storage
Daemon.

Akin to the :module: override option, the :namespace: options allows you
to forcibly override the contextual namespace associatied with a
definition.
We don't necessarily actually need this, but I felt compelled to stick
close to how the Python domain works that offers context overrides.
As of this commit, it is possible to add e.g. ":namespace: QMP" to any
QAPI directive to forcibly associate that definition with a given
namespace.

Add "the members of ..." pointers to Members and Arguments lists where
appropriate, with clickable cross-references - so it's a slight
improvement over the old system :)
This patch is meant to be a temporary solution until we can review and
merge the inliner.
The implementation of this patch is a little bit of a hack: Sphinx is
not designed to allow you to mix fields of different "type"; i.e. mixing
member descriptions and free-form text under the same heading. To
accomplish this with a minimum of hackery, we technically document a
"dummy field" and then just strip off the documentation for that dummy
field in a post-processing step. We use the "q_dummy" variable for this
purpose, then strip it back out before final processing. If this
processing step should fail, you'll see warnings for a bad
cross-reference. (So if you don't see any, it must be working!)

We have several kinds of sections, and to tell them apart, we use
Section attribute @tag and also the section object's Python type:
type @tag
untagged Section None
@foo: ArgSection 'foo'
Returns: Section 'Returns'
Errors: Section 'Errors'
Since: Section 'Since'
TODO: Section 'TODO'
Note:
* @foo can be a member or a feature description, depending on context.
* tag == 'Since' can be a Since: section or a member or feature
description. If it's a Section, it's the former, and if it's an
ArgSection, it's the latter.
Clean this up as follows. Move the member or feature name to new
ArgSection attribute @name, and replace @tag by enum @kind like this:
type kind name
untagged Section PLAIN
@foo: ArgSection MEMBER 'foo' if member or argument
ArgSection FEATURE 'foo' if feature
Returns: Section RETURNS
Errors: Section ERRORS
Since: Section SINCE
TODO: Section TODO
The qapi-schema tests are updated to account for the new section names;
"TODO" becomes "Todo" and `None` becomes "Plain" there.

Sphinx 5.3.0 to Sphinx 6.2.0 has a bug where nested content in an
ObjectDescription content block has its error position reported
incorrectly due to an oversight when they added nested section support
to this directive.
(This bug is present in Sphinx's own Python and C domains; test it
yourself by creating a py:func directive and creating a syntax error in
the directive's content block. The reporting will be incorrect.)
To avoid overriding and re-implementing the entirety of the run()
method, a workaround is employed where we parse the content block
ourselves in before_content(), then null the content block to make
Sphinx's own parsing a no-op. Then, in transform_content (which occurs
after Sphinx's nested parse), we simply swap our own parsed content tree
back in for Sphinx's.
It appears a little tricky, but it's the nicest solution I can find.

This commit, finally, adds cross-referencing support to various field
lists; modeled tightly after Sphinx's own Python domain code.
Cross-referencing support is added to type names provided to :arg:,
:memb:, :returns: and :choice:.
:feat:, :error: and :value:, which do not take type names, do not
support this syntax.
The general syntax is simple:
:arg TypeName ArgName: Lorem Ipsum ...
The domain will transform TypeName into :qapi:type:`TypeName` in this
basic case, and also apply the ``literal`` decoration to indicate that
this is a type cross-reference.
For optional arguments, the special "?" suffix is used. Because "*" has
special meaning in rST that would cause parsing errors, we elect to use
"?" instead. The special syntax processing strips this character from
the end of any type name argument and will append ", optional" to the
rendered output, applying the cross-reference only to the actual type
name.
The intent here is that the actual syntax in doc-blocks need not change;
but e.g. qapidoc.py will need to process and transform "@arg foo lorem
ipsum" into ":arg type? foo: lorem ipsum" based on the schema
information. Therefore, nobody should ever actually witness this
intermediate syntax unless they are writing manual documentation or the
doc transmogrifier breaks.
For array arguments, type names can similarly be surrounded by "[]",
which are stripped off and then re-appended outside of the
cross-reference.

Normally, Sphinx will silently fall back to its standard field list
processing if it doesn't match one of your defined fields. A lot of the
time, that's not what we want - we want to be warned if we goof
something up.
For instance, the canonical argument field list form is:
:arg type name: descr
This form is captured by Sphinx and transformed so that the field label
will become "Arguments:". It's possible to omit the type name and descr
and still have it be processed correctly. However, if you omit the type
name, Sphinx no longer recognizes it:
:arg: this is not recognized.
This will turn into an arbitrary field list entry whose label is "Arg:",
and it otherwise silently fails. You may also see failures for doing
things like using :values: instead of :value:, or :errors: instead of
:error:, and so on. It's also case sensitive, and easy to trip up.
Add a validator that guarantees all field list entries that are the
direct child of an ObjectDescription use only recognized forms of field
lists, and emit a warning (treated as error by default in most build
configurations) whenever we detect one that is goofed up.
However, there's still benefit to allowing arbitrary fields -- they are
after all not a Sphinx invention, but perfectly normal docutils
syntax. Create an allow list for known spellings we don't mind letting
through, but warn against anything else.

Like "Arguments:" and "Errors:", the type name isn't currently processed
for cross-referencing, but this will be addressed in a forthcoming
commit.
The syntax of the new field is:
:return TypeName: description
description cont'd
This patch adds "Return" as a GroupedField, which means that multiple
return values can be annotated - this is only done because Sphinx does
not support mandatory type arguments to Ungrouped fields. Because we
want to cross-reference this type information later, we want to make the
type argument mandatory. As a result, you can technically add multiple
:return: fields, though I'm not aware of any circumstance in which you'd
need or want to. Recommendation: "Don't do that, then." The forthcoming
QAPIDoc transmogrifier does not, in fact, ever "do that".

``:error: descr`` can now be used to document error conditions. The
format of the description is not defined here; so the ability to name
specific types is left to the document writer.

Add support for Features field lists. There is no QAPI-specific
functionality here, but this could be changed if desired (if we wanted
the feature names to link somewhere, for instance.)
This feature list doesn't have any restrictions, so it can be used to
document object-wide features or per-member features as deemed
appropriate. It's essentially free-form text.
The syntax for this field is:
:feat name: description
description cont'd

This adds special rendering for Sphinx's typed info field lists.
This patch does not add any QAPI-aware markup, rendering, or
cross-referencing for the type names, yet. That feature requires a
subclass to TypedField which will happen in its own commit quite a bit
later in this series; after all the basic fields and objects have been
established first.
The syntax for this field is:
:arg type name: description
description cont'd
You can omit the type or the description. You should not omit the name;
if you do so, it degenerates into a "normal field list" entry, and
probably isn't what you want.

Add a little special markup for registering "Since:" information. Adding
it as an option instead of generic content lets us hoist the information
into the Signature bar, optionally put it in the index, etc.

This commit adds a stubbed version of QAPICommand that utilizes the
QAPIObject class, the qapi:command directive, the :qapi:cmd:
cross-reference role, and the "command" object type in the QAPI object
registry.
They don't do anything *particularly* interesting yet, but that will
come in forthcoming commits.

This patch adds another abstract class that describes "a QAPI
thingie". The main difference here is that this class will be generating
visible documentation, unlike the QAPIDescription class.

This adds the qapi:module directive, which just notes the current module
being documented and performs a nested parse of the content block, if
present.
This code is based pretty heavily on Sphinx's PyModule directive, but
with unnecessary features excised.
For example:
.. qapi:module:: block-core
Hello, and welcome to block-core!
=================================
lorem ipsum, dolor sit amet ...

This class is a generic, top-level directive for documenting some kind
of QAPI thingamajig that we expect to go into the Index. This class
doesn't do much by itself, and it isn't yet associated with any
particular directive.
handle_signature(), _object_hierarchy_parts() and _toc_entry_name() are
defined in the base class. get_index_text() and add_target_and_index()
are new methods defined here; they are based heavily on the layout and
format of the Python domain's general object class.

Sphinx prior to v4.0 uses different classes for rendering elements of
documentation objects; add some compatibility classes to use the right
node classes conditionally.
