Alex Bennée 171080d891 testing: update ubuntu2004 to ubuntu2204
The 22.04 LTS release has been out for almost a year now so its time
to update all the remaining images to the current LTS. We can also
drop some hacks we need for older clang TSAN support.

We will keep the ubuntu2004 container around for those who wish to
test builds on the currently still supported baseline.

Paolo Bonzini 32c0613113 ci, docker: update CentOS and OpenSUSE Python to non-EOL versions
Python 3.6 is at end-of-life.  Update the libvirt-ci module to a
version that supports overrides for targets and package mappings;
this way, QEMU can use the newer versions provided by CentOS 8 (Python
3.8) and OpenSUSE 15.3 (Python 3.9).

Paolo Bonzini fa1ce1dda9 docs/devel: update and clarify lcitool instructions
Shorten a bit the description of what libvirt-ci does, the name of the
data files is not relevant at that point.  However, the procedures to add
new build prerequisites are lacking some information, particularly with
respect to regenerating the output test files for lcitool's unit tests.
While at it, also update the paths in the libvirt-ci repository.

John Snow 1b1be8d3cc meson: stop looking for 'sphinx-build-3'
Once upon a time, "sphinx-build" on certain RPM platforms invoked
specifically a Python 2.x version, while "sphinx-build-3" was a distro
shim for the Python 3.x version.

These days, none of our supported platforms utilize a 2.x version, and
those that still have 'sphinx-build-3' make it a symbolic link to
'sphinx-build'.  Not searching for 'sphinx-build-3' will prefer
pip/venv installed versions of sphinx if they're available.

This adds an extremely convenient ability to test document building
ability in QEMU across multiple versions of Sphinx for the purposes of
compatibility testing.

Steve Sistare adf4c9bd2e meson: fix dependency on qemu-keymap
When qemu-keymap is not available on the host, and enable-xkbcommon
is specified, parallel make fails with:

  % make clean
  ...
  % make -j 32
  ...
  FAILED: pc-bios/keymaps/is
  ./qemu-keymap -f pc-bios/keymaps/is -l is
  /bin/sh: ./qemu-keymap: No such file or directory
  ... many similar messages ...

The code always runs find_program, rather than waiting to build
qemu-keymap, because it looks for CONFIG_XKBCOMMON in config_host
rather than config_host_data.  Making serially succeeds, by soft
linking files from pc-bios/keymaps, but that is not the desired
result for enable-xkbcommon.

Examining all occurrences of 'in config_host' for similar bugs shows one
instance in the docs, which is also fixed here.

Fixes: 4113f4cfee ("meson: move xkbcommon to meson")

Paolo Bonzini 8d0efbcfa0 docs: build-platforms: refine requirements on Python build dependencies
Historically, the critical dependency for both building and running
QEMU has been the distro packages.  Because QEMU is written in C and C's
package management has been tied to distros (at least if you do not want
to bundle libraries with the binary, otherwise I suppose you could use
something like conda or wrapdb), C dependencies of QEMU would target the
version that is shipped in relatively old but still commonly used distros.

For non-C libraries, however, the situation is different, as these
languages have their own package management tool (cpan, pip, gem, npm,
and so on).  For some of these languages, the amount of dependencies
for even a simple program can easily balloon to the point that many
distros have given up on packaging non-C code.  For this reason, it has
become increasingly normal for developers to download dependencies into
a self-contained local environment, instead of relying on distro packages.

Fortunately, this affects QEMU only at build time, as qemu.git does
not package non-C artifacts such as the qemu.qmp package; but still,
as we make more use of Python, we experience a clash between a support
policy that is written for the C world, and dependencies (both direct
and indirect) that increasingly do not care for the distro versions
and are quick at moving past Python runtime versions that are declared
end-of-life.

For example, Python 3.6 has been EOL'd since December 2021 and Meson 0.62
(released the following March) already dropped support for it.  Yet,
Python 3.6 is the default version of the Python runtime for RHEL/CentOS
8 and SLE 15, respectively the penultimate and the most recent version
of two distros that QEMU would like to support.  (It is also the version
used by Ubuntu 18.04, but QEMU stopped supporting it in April 2022).

There are good reasons to move forward with the deprecation of Python
3.6 in QEMU as well: completing the configure->meson switch (which
requires Meson 0.63), and making the QAPI generator fully typed (which
requires newer versions of not just mypy but also Python, due to PEP563).

Fortunately, these long-term support distros do include newer versions of
the Python runtime.  However, these more recent runtimes only come with
a very small subset of the Python packages that the distro includes.
Because most dependencies are optional tests (avocado, mypy, flake8)
and Meson is bundled with QEMU, the most noticeably missing package is
Sphinx (and the readthedocs theme).  There are four possibilities:

* we change the support policy and stop supporting CentOS 8 and SLE 15;
  not a good idea since CentOS 8 is not an unreasonable distro for us to
  want to continue to support

* we keep supporting Python 3.6 until CentOS 8 and SLE 15 stop being
  supported.  This is a possibility---but we may want to revise the support
  policy anyway because SLE 16 has not even been released, so this would
  mean delaying those desirable reasons for perhaps three years;

* we support Python 3.6 just for building documentation, i.e. we are
  careful not to use Python 3.7+ features in our Sphinx extensions but are
  free to use them elsewhere.  Besides being more complicated to understand
  for developers, this can be quite limiting; parts of the QAPI generator
  run at sphinx-build time, which would exclude one of the areas which
  would benefit from a newer version of the runtime;

* we only support Python 3.7+, which means CentOS 8 CI and users
  have to either install Sphinx from pip or disable documentation.

This proposed update to the support policy chooses the last of these
possibilities.  It does by modifying three aspects of the support
policy:

* it introduces different support periods for *native* vs. *non-native*
  dependencies.  Non-native dependencies are currently Python ones only,
  and for simplicity the policy only mentions Python; however, the concept
  generalizes to other languages with a well-known upstream package
  manager, that users of older distributions can fetch dependencies from;

* it opens up the possibility of taking non-native dependencies from their
  own package index instead of using the version in the distribution.  The
  wording right now is specific to dependencies that are only required at
  build time.  In the future we may have to refine it if, for example, parts
  of QEMU will be written in Rust; in that case, crates would be handled
  in a similar way to submodules and vendored in the release tarballs.

* it mentions specifically that optional build dependencies are excluded
  from the platform policy.  Tools such as mypy don't affect the ability
  to build QEMU and move fast enough that distros cannot standardize on
  a single version of them (for example RHEL9 does not package them at
  all, nor does it run them at rpmbuild time).  In other cases, such as
  cross compilers, we have alternatives.

Right now, non-native dependencies have to be download manually by
running "pip" before "configure".  In the future, it will be desirable
for configure to set up a virtual environment and download them in the
same way that it populates git submodules (but, in this case, without
vendoring them in the release tarballs).

Just like with submodules, this would make things easier for people
that can afford accessing the network in their build environment; the
option to populate the build environment manually would remain for
people whose build machines lack network access.  The change to the
support policy neither requires nor forbids this future change.

Alex Bennée 2c46bc240a docs: add an introduction to the system docs
Drop the frankly misleading quickstart section for a more rounded
introduction section. This new section gives an overview of the
accelerators as well as a high level introduction to some of the key
features of the emulator. We also expand on a general form for a QEMU
command line with a hopefully not too scary worked example of what
this looks like.

Alex Bennée 2da9d21360 semihosting: add semihosting section to the docs
The main reason to do this is to document our O_BINARY implementation
decision somewhere. However I've also moved some of the implementation
details out of qemu-options and added links between the two. As a
bonus I've highlighted the scary warnings about host access with the
appropriate RST tags.

Thomas Huth 90c167a1da docs/about/deprecated: Mark HAXM in QEMU as deprecated
The HAXM project has been retired (see https://github.com/intel/haxm#status),
so we should mark the code in QEMU as deprecated (and finally remove it
unless somebody else picks the project up again - which is quite unlikely
since there are now whpx and hvf on these operating systems, too).
