python: Install pycotap in our venv if necessary

The upcoming functional tests will require pycotap for providing
TAP output from the python-based tests. Since we want to be able
to run some of the tests offline by default, too, let's install
it along with meson in our venv if necessary (it's size is only
5 kB, so adding the wheel here should not really be a problem).

The wheel file has been obtained with:

pip download --only-binary :all: --dest . --no-cache pycotap

Bump avocado to 103.0

This bumps Avocado to latest the LTS release.

An LTS release is one that can receive bugfixes and guarantees
stability for a much longer period and has incremental minor releases
made.

Even though the 103.0 LTS release is pretty a rewrite of Avocado when
compared to 88.1, the behavior of all existing tests under
tests/avocado has been extensively tested no regression in behavior
was found.

To keep behavior of jobs as close as possible with previous version,
this version bump keeps the execution serial (maximum of one task at a
time being run).

Python: bump minimum sphinx version to 3.4.3

With RHEL 8 support retired (It's been two years since RHEL9 released),
our very oldest build platform version of Sphinx is now 3.4.3; and
keeping backwards compatibility for versions as old as v1.6 when using
domain extensions is a lot of work we don't need to do.

This patch is motivated by my work creating a new QAPI domain, which
unlike the dbus documentation, cannot be allowed to regress by creating
a "dummy" doc when operating under older sphinx versions. Easier is to
raise our minimum version as far as we can push it forwards, reducing my
burden in creating cross-compatibility hacks and patches.

OpenSUSE Leap 15.4: EOL
OpenSUSE Leap 15.5: 2.3.1, 4.2.0 and 7.2.6

RHEL9 / CentOS Stream 9 becomes the new defining factor in staying at
Sphinx 3.4.3 due to downstream offline build requirements that force us
to use platform Sphinx instead of newer packages from PyPI.

meson: Pass objects and dependencies to declare_dependency()

We used to request declare_dependency() to link_whole static libraries.
If a static library is a thin archive, GNU ld keeps all object files
referenced by the archive open, and sometimes exceeds the open file limit.

Another problem with link_whole is that suboptimal handling of nested
dependencies.

link_whole by itself does not propagate dependencies. In particular,
gnutls, a dependency of crypto, is not propagated to its users, and we
currently workaround the issue by declaring gnutls as a dependency for
each crypto user. On the other hand, if you write something like

libfoo = static_library('foo', 'foo.c', dependencies: gnutls)
foo = declare_dependency(link_whole: libfoo)

libbar = static_library('bar', 'bar.c', dependencies: foo)
bar = declare_dependency(link_whole: libbar, dependencies: foo)
executable('prog', sources: files('prog.c'), dependencies: [foo, bar])

hoping to propagate the gnutls dependency into bar.c, you'll see a
linking failure for "prog", because the foo.c.o object file is included in
libbar.a and therefore it is linked twice into "prog": once from libfoo.a
and once from libbar.a. Here Meson does not see the duplication, it
just asks the linker to link all of libfoo.a and libbar.a into "prog".

Instead of using link_whole, extract objects included in static libraries
and pass them to declare_dependency(); and then the dependencies can be
added as well so that they are propagated, because object files on the
linker command line are always deduplicated.

This requires Meson 1.1.0 or later.

"good enough" packaged wheel.

Revert "tests: Use separate virtual environment for avocado"

Revert "tests: Use separate virtual environment for avocado"

This reverts commit e8e4298feadae7924cf7600bb3bcc5b0a8d7cbe9.

ensuregroup allows to specify both the acceptable versions of avocado,
and a locked version to be used when avocado is not installed as a system
pacakge. This lets us install avocado in pyvenv/ using "mkvenv.py" and
reuse the distro package on Fedora and CentOS Stream (the only distros
where it's available).

ensuregroup's usage of "(>=..., <=...)" constraints when evaluating
the distro package, and "==" constraints when installing it from PyPI,
makes it possible to avoid conflicts between the known-good version and
a package plugins included in the distro.

This is because package plugins have "==" constraints on the version
that is included in the distro, and, using "pip install avocado==88.1"
on a venv that includes system packages will result in an error:

avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.

But at the same time, if the venv does not include a system distribution
of avocado then we can install a known-good version and stick to LTS
releases.

configure: switch to ensuregroup

Using the new ensuregroup command, the desired versions of meson and
sphinx can be placed in pythondeps.toml rather than configure.

The meson.install entry in pythondeps.toml matches the version that is
found in python/wheels. This ensures that mkvenv.py uses the bundled
wheel even if PyPI is enabled; thus not introducing warnings or errors
from versions that are more recent than the one used in CI.

The sphinx entries match what is shipped in Fedora 38. It's the
last release that has support for older versions of Python (sphinx 6.0
requires Python 3.8) and especially docutils (of which sphinx 6.0 requires
version 0.18). This is important because Ubuntu 20.04 has docutils 0.14
and Debian 11 has docutils 0.16.

"mkvenv.py ensure" is only used to bootstrap tomli.

python: mkvenv: add ensuregroup command

Introduce a new subcommand that retrieves the packages to be installed
from a TOML file. This allows being more flexible in using the system
version of a package, while at the same time using a known-good version
when installing the package. This is important for packages that
sometimes have backwards-incompatible changes or that depend on
specific versions of their dependencies.

Compared to JSON, TOML is more human readable and easier to edit. A
parser is available in 3.11 but also available as a small (12k) package
for older versions, tomli. While tomli is bundled with pip, this is only
true of recent versions of pip. Of all the supported OSes pretty much
only FreeBSD has a recent enough version of pip while staying on Python
<3.11. So we cannot use the same trick that is in place for distlib.
