[PATCH v3 00/63] docs: Add new QAPI transmogrifier

[John Snow <jsnow@redhat.com>]

This series is a "minimum viable" version of the new QAPI documentation
system. It does the bare minimum under the new framework, saving the
fancy features like the inliner for later. This version does add
cross-references for all QAPI definitions and a shiny new QAPI Index.

Patches 3-31 implement the qapi_domain extension.
Patches 32-59 implement the qapidoc "Transmogrifier".

Known shortcomings in this series:

- Some ifcond information (features, members) is still not displayed.
- No QAPI namespace support ... yet. So we can't enable it for QMP, QGA
  and QSD simultaneously just yet. It's nearly complete.

v3:

- Moved a few more methods from QAPIObject to QAPIDescription
- Implemented most of the rest of Markus' feedback.

v2:

- Did you know that my computer just shut off the moment I started
  sending the patchset? Just a hard off. Wow!
- Refactored QAPIObject class so that QAPIModule uses more of
Sphinx's ObjectDescription class, which means less fooling around with
re-parsing Sphinx standard options.
- Removed test document, flipped switch on the real QMP manual.
- Undocumented members have been re-added. I think that's new for this version!
- Removed some inliner branch code that snuck into the "validate info
  fields" patch.
- Lots of Markus' feedback, and misc changes.

"v1":

- @foo is processed into ``foo`
- "The members of ..." messages have been temporarily re-added until we
  can smooth over the inliner.
- This series runs under Sphinx 3.4.3 to Sphinx 8.2.0 inclusive. It
  truly is a Christmas miracle. (please clap)
- This series now fully type checks and lint checks under Sphinx 8.2.0,
  but may not type check under earlier Sphinx versions. Achieving this
  alone, nevermind in conjunction with the above, was a literal
  herculean labor.
