Peter Maydell 758b617af8 configure: Check that sphinx-build is using Python 3
Currently configure's has_sphinx_build() check simply runs a dummy
sphinx-build and either passes or fails.  This means that "no
sphinx-build at all" and "sphinx-build exists but is too old" are
both reported the same way.

Further, we want to assume that all the Python we write is running
with at least Python 3.5; configure checks that for our scripts, but
Sphinx extensions run with whatever Python version sphinx-build
itself is using.

Add a check to our conf.py which makes sphinx-build fail if it would
be running our extensions with an old Python, and handle this
in configure so we can report failure helpfully to the user.
This will mean that configure --enable-docs will fail like this
if the sphinx-build provided is not suitable:

Warning: sphinx-build exists but it is either too old or uses too old a Python version

ERROR: User requested feature docs
       configure was not able to find it.
       Install texinfo, Perl/perl-podlators and a Python 3 version of python-sphinx

(As usual, the default is to simply not build the docs, as we would
if sphinx-build wasn't present at all.)

Peter Maydell 6803d6e9a7 docs/sphinx: Add new hxtool Sphinx extension
Some of our documentation includes sections which are created
by assembling fragments of texinfo from a .hx source file into
a .texi file, which is then included from qemu-doc.texi or
qemu-img.texi.

For Sphinx, rather than creating a file to include, the most natural
way to handle this is to have a small custom Sphinx extension which
reads the .hx file and process it.  So instead of:
 * makefile produces foo.texi from foo.hx
 * qemu-doc.texi says '@include foo.texi'
we have:
 * qemu-doc.rst says 'hxtool-doc:: foo.hx'
 * the Sphinx extension for hxtool has code that runs to handle that
   Sphinx directive which reads the .hx file and emits the appropriate
   documentation contents

This is pretty much the same way the kerneldoc extension works right
now. It also has the advantage that it should work for third-party
services like readthedocs that expect to build the docs directly with
sphinx rather than by invoking our makefiles.

In this commit we implement the hxtool extension.

Note that syntax errors in the rST fragments will be correctly
reported to the user with the filename and line number within the
hx file.

 * a section of the main qemu-doc HTML documentation

Convert the documentation to rST format, and present it to
the user as:
 * a qemu-ga manpage
 * part of the interop/ Sphinx manual

John Snow cd231e13bd sphinx: add qmp_lexer
Sphinx, through Pygments, does not like annotated json examples very
much. In some versions of Sphinx (1.7), it will render the non-json
portions of code blocks in red, but in newer versions (2.0) it will
throw an exception and not highlight the block at all. Though we can
suppress this warning, it doesn't bring back highlighting on non-strict
json blocks.

We can alleviate this by creating a custom lexer for QMP examples that
allows us to properly highlight these examples in a robust way, keeping
our directionality and elision notations.

Peter Maydell 6038f5fca5 docs/conf.py: Don't hard-code QEMU version
Don't hard-code the QEMU version number into conf.py. Instead
we either pass it to sphinx-build on the command line, or
(if doing a standalone Sphinx run in a readthedocs.org setup)
extract it from the VERSION file.

Peter Maydell f8cf7147f1 docs: Provide separate conf.py for each manual we want
By default Sphinx wants to build a single manual at once.
For QEMU, this doesn't suit us, because we want to have
separate manuals for "Developer's Guide", "User Manual",
and so on, and we don't want to ship the Developer's Guide
to end-users. However, we don't want to completely duplicate
conf.py for each manual, and we'd like to continue to
support "build all docs in one run" for third-party sites
like readthedocs.org.

Make the top-level conf.py support two usage forms:
 (1) as a common config file which is included by the conf.py
 for each of QEMU's manuals: in this case sphinx-build is run
 multiple times, once per subdirectory.
 (2) as a top level conf file which will result in building all
 the manuals into a single document: in this case sphinx-build is
 run once, on the top-level docs directory.

Provide per-manual conf.py files and top level pages for
our first two manuals:
 * QEMU Developer's Guide (docs/devel)
 * QEMU System Emulation Management and Interoperability Guide
   (docs/interop)

Peter Maydell e250e867dc docs/conf.py: Disable option warnings
sphinx-build complains about using :option: to mark up option
flags that it doesn't know about (because they were not defined
using the "option::" directive):
docs/pr-manager.rst:68: WARNING: unknown option: -d

Suppress these warnings. This way we get the semantic markup
of the option flag but no cross-referencing hyperlink.
