Earlier version 1.22.0 does not support recent setuptools.

Latest version 1.26.2 has more complex build requirements,
left for later.

Now that buildout uses pip to correctly follow pyproject.toml,
cattrs=22.2.0 requires poetry as the build backend.

For now it's easier to install as wheel than to install poetry and
then use it as setup-egg for cattrs. This must be done eventually.

zc.buildout=2.7.1+slapos020 is SlapOS-patched buildout2 with support
for bootstrapping buildout3, required to be able to install buildout3.

Downgrade related eggs to pre-buildout3 versions as well.

Version up zc.buildout, pip and zc.recipe.egg.

Version up slapos.rebootstrap to adapt to buildout3.

With newer setuptools that is coming via nexedi/slapos!1550 (44.1.1 -> 67.8.0)
we will need a fix from setuptools-dso 2.10 to handle `python setup develop` well:

Previously with setutools-dso 2.9 and setuptools 67.8.0 built shared libraries were not
copied back into the working tree upon develop install which made anything
using pygolang to fail as e.g.

    $ ../bin/gpython
    Traceback (most recent call last):
      File ".../../bin/gpython", line 20, in <module>
        sys.exit(gpython.main())
      File ".../pygolang/gpython/__init__.py", line 456, in main
        pymain(argv, init)
      File ".../pygolang/gpython/__init__.py", line 223, in pymain

See https://github.com/mdavidsaver/setuptools_dso/pull/29#issuecomment-1745790761
and https://github.com/mdavidsaver/setuptools_dso/commit/2fdf75f2 for details.

P.S. NOTE that changing version of a setup-egg required egg currently does
_not_ force a rebuild. In other words pushing this change into testnodes won't
make pygolang t o be rebuilt at all. I think this is simply a bug in
slapos.buildout to fix.

This is done as an alternative to the patch in !1580, as the last
version is already patched.

without this change, configure would use openssl lib for MD5, sha256sum, ...
if openssl development files are present on the system.

Previously, zstd support was only compiled if zstlib was installed in
the system.

This especially brings support for systems where 'model name' is not
present in /proc/cpuinfo

the previous version was failing like this if lib64 doesn't exist:

libcap: Command 'set -e;cd /opt/slapgrid/shared/libcap/4d09237abd7cb34117fccc1d3c3bc862
[ -d lib64 ] && ln -s lib64 lib' returned non-zero exit status 1

option --enable-readline doesn't exist anymore (has it ever?)

We need to add option --disable-initial-exec-tls because we hit the bug
shown in https://github.com/jemalloc/jemalloc/issues/937 with mariadb:

We now need to install lxml-clean-html separately, see the following

We need to patch ffmpeg to be able to compile with this version of
binutils.

Currently libsnappy is being compiled in the folder lib64 in some
OSes (e.g. SUSE SLE 15.6).
This is a problem because some dependents look for the library in the
lib subdirectory.
This change forces snappy to always use the lib directory.

This is a follow-up of 7a1ba8df.

because re6stnet only supports OpenVPN 2.4.
This reverts commit 6802867d.

When compiling older GCC versions in newer machines, libsanitizer
does not compile, showing a error: `multiple definition of
'enum fsconfig_command'` (e.g.
https://github.com/llvm/llvm-project/issues/56421).
This is because starting from Glibc 2.36, it is not possible to include
both "linux/fs.h" and "sys/mount.h".

We can apply a patch, similar to the one in
https://reviews.llvm.org/D129471 , but with the extension and lines
changed to match the file. This is also similar to the upstream fix.

This will be used to add the sqlite3 binary directory to PATH.

This now supports producing html reports directly

nbd2-host and nbd2-port are asserted too.

Test are reorganized to easily assert mixed scenarios.
