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!

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.

Add domain-specific cross-reference syntax. As of this commit, that
means new :qapi:any:`block-core` referencing syntax.
The :any: role will find anything registered to the QAPI domain,
including modules, commands, events, etc.
Creating the cross-references is powered by the QAPIXRefRole class;
resolving them is handled by QAPIDomain.resolve_xref().
QAPIXrefRole is based heavily on Sphinx's own PyXrefRole, with
modifications necessary for QAPI features.

Add the ability to resolve cross-references using the `any`
cross-reference syntax. Adding QAPI-specific cross-reference roles will
be added in a forthcoming commit, and will share the same find_obj()
helper.
(There's less code needed for the generic cross-reference resolver, so
it comes first in this series.)
Once again, this code is based very heavily on sphinx.domains.python.

Use the QAPI object registry to generate a special index just for QAPI
definitions. The index can show entries both by definition type and all
together, alphabetically.
The index can be linked from anywhere in the QEMU manual by using the
reference `qapi-index`.

This is the first step towards QAPI domain cross-references and a QAPI
reference index.
This patch just creates the object registry, and updates the
merge_domaindata stub method now that we have actual data we may need to
merge.
Note that how to handle merge conflict resolution is unhandled, as the
Sphinx python domain itself does not handle it either. I do not know how
to intentionally trigger it, so I've left an assertion instead if it
should ever come up ...

A Sphinx domain is a collection of directive and role extensions meant
to facilitate the documentation of a specific language. For instance,
Sphinx ships with "python" and "cpp" domains. This patch introduces a
stub for the "qapi" language domain.
Please see https://www.sphinx-doc.org/en/master/usage/domains/index.html
for more information.
This stub doesn't really do anything yet, we'll get to it brick-by-brick
in the forthcoming commits to keep the series breezy and the git history
informative.
