All our supported build platforms have Python 3.6 or newer nowadays, and
there are some useful features in Python 3.6 which are not available in
3.5 yet (e.g. the type hint annotations which will allow us to statically
type the QAPI parser), so let's bump the minimum Python version to 3.6 now.

Some of our documentation is auto-generated from documentation
comments in the JSON schema.
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
processes the JSON file and inserts documentation into the rST
file being processed.
This is the same approach that kerneldoc and hxtool use.

Versions of Sphinx older than 1.6 can't build all of our documentation,
because they are too picky about the syntax of the argument to the
option:: directive; see Sphinx bugs #646, #3366:
https://github.com/sphinx-doc/sphinx/issues/646
https://github.com/sphinx-doc/sphinx/issues/3366
Trying to build with a 1.4.x Sphinx fails with
docs/system/images.rst:4: SEVERE: Duplicate ID: "cmdoption-qcow2-arg-encrypt"
and a 1.5.x Sphinx fails with
docs/system/invocation.rst:544: WARNING: Malformed option description '[enable=]PATTERN', should look like "opt", "-opt
args", "--opt args", "/opt args" or "+opt args"
Update our needs_sphinx setting to indicate that we require at least
1.6. This will allow configure to fall back to "don't build the
docs" rather than causing the build to fail entirely, which is
probably what most users building on a host old enough to have such
an old Sphinx would want; if they do want the docs then they'll have
a useful indication of what they need to do (upgrade Sphinx!) rather
than a confusing error message.
In theory our distro support policy would suggest that we should
support building on the Sphinx shipped in those distros, but:
* EPEL7 has Sphinx 1.2.3 (which we've never supported!)
* Debian Stretch has Sphinx 1.4.8
Trying to get our docs to work with Sphinx 1.4 is not tractable
for the 5.0 release and I'm not sure it's worthwhile effort anyway;
at least with this change the build as a whole now succeeds.
Thanks to John Snow for doing the investigation and testing to
confirm what Sphinx versions fail in what ways and what distros
shipped what.

Raise ConfigError rather than VersionRequirementError when we detect
that the Python being used by Sphinx is too old.
Currently the way we flag the Python version problem up to the user
causes Sphinx to print an unnecessary Python stack trace as well as
the information about the problem; in most versions of Sphinx this is
unavoidable.
The upstream Sphinx developers kindly added a feature to allow
conf.py to report errors to the user without the backtrace:
https://github.com/sphinx-doc/sphinx/commit/be608ca2313fc08eb842f3dc19d0f5d2d8227d08
but the exception type they chose for this was ConfigError.
Switch to ConfigError, which won't make any difference with currently
deployed Sphinx versions, but will be prettier one day when the user
is using a Sphinx version with the new feature.

Rather than accumulating generally useful rST substitution
definitions in individual rST files, create a defs.rst.inc where we
can define these. To start with it has the |qemu_system| definition
from qemu-block-drivers.rst.
Add a comment noting a pitfall where putting literal markup in the
definition of |qemu_system| makes it misrender manpage output; this
means the point-of-use must handle the literal markup (which is
almost always done by having it inside a parsed-literal block).

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.)

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.

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.

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)

sphinx-build complains about using :option: to mark up option

using the "option::" directive):
