wendelin.core 2.0.alpha3.post9 supports golang 1.21: with this new
version we can set golang 1.21 as the new default.

/reviewed-by @kirr and @jerome
/reviewed-on nexedi/slapos!1494

Go1.21 already has the fifth minor revision (released 2023-12-05) and
should therefore already be sufficiently stable. Furthermore we need it
to fix a bug in a NEO/go dependency [1].

Please find all details in the official release note:

    https://go.dev/doc/go1.21

It was released on 2023-08-08 [2]. Due to the go promise of compatibility
most software should still compile without any problems.

In golang < 1.21 we needed to patch golang to fix
https://github.com/golang/go/issues/42525. In golang 1.21 we still need
to apply a fix, but can't apply the old patch because the code changed.
In golang > 1.21 this problem is already fixed with https://go-review.googlesource.com/c/go/+/520055.

Because of https://github.com/golang/go/commit/092671423cd95eaa6df93eb29442fef41504d097
'TestUnshareMountNameSpace' fails on golang 1.21 [3]. In golang 1.20 this test
was skipped [4]. To fix this failure the additional patch
'skip-unshare-mount-test.patch' has been added.

This version is compatible with gcc 12

using https://github.com/ilevkivskyi/com2ann

drop versions not running on debian 12 and add new versions

This was disabled to "keep compatibility with current font selection
problems", but I don't think we need to care about compatibility for
this. This was anyway causing a problem that system fontconfig will be
used if it's available, so it's better to define things explictly to
prevent falling back to system configuration.

This caused cloudooo to select different fonts, because LibreOffice-bin
comes with some Noto fonts and fontconfig now prefers Noto font

Testing conversion of HTML with font-family:"FontFamily FontVariant"
CSS rule does not really make sense. Remove a few cases for which the
behavior is not stable.

Using RegExp to validate hostnames is a bad practice, and has a lot of reasons to be wrong.
On top of that, the JSON Schema specification allows, since draft 7, to validate hostnames
against an IDN hostname, by using the `idn-hostname` format.

With these changes, IDN are now supported (.рф and .中國 for instance), and long TLD
should not be a problem anymore.

With backported fixes so that old software supports debian 12

In 9636d79c (Nextcloud Upgrade fixes, 2023-12-13) parameter changed:
 - instance.trusted-domain-* parameters are replaced by instance.trusted-domain-list
 - the frontend is part of trusted domain, so with "bypassed" frontends
from slapos proxy the backend appears twice (because the backend URL is
returned as frontend URL)

This actually updates firefox from version 68 to version 115

So that we can see when something changes.

See merge request nexedi/slapos!1486

Use runTestSuite interface to launch tests that request instances
on actual SlapOS cloud.

As described in https://github.com/msgpack/msgpack-python#major-breaking-changes-in-msgpack-10
raw is False by default for unpacker so we receive strings, not bytes

ZODB4 does not support python3

These must be installed through dependencies, but we explicitly need
scripts from supervisor because this is used by slapos-core tests

on python3 we use lzma directly

This software only use nodejs for a simple build step, it should be OK
to use any version.

Hello up there.

I've noticed that wendelin.core tests became failing to build and
automatically disabled some time ago. Not good. I've tried to fix build
failures. Please see individual patches for details.

After probably 02fad6a8 (component/{numpy,scipy}: Version up for Python3.)
pygolang test build started to fail in numpy compilation as shown in the
appendix. The failure is correct as pygolang never explicitly depended on
${numpy:egg}. We did not noticed before probably because in earlier versions
numpy did not required Cython to be present at install time.

-> Fix it by explicitly adding ${numpy:egg} to pygolang[all_test] dependencies.

I already fixed ZEO4-wc2 installation once in 97832d95 (ZEO: Fix
ZEO4-wc2 installation). That worked but, as it turned out, not fully:
Even though correct ZEO4-wc2-repository is cloned, and correct ZEO4-wc2
develop-egg is installed, we don't tell buildout which egg-version of
ZEO to use. This leads to the situation when buildout picks up _latest_
ZEO egg, when another egg, which depends on ZEO, is installed.

-> Fix that by specifying which egg-version ZEO4/ZEO4-wc2 should be using.

For the reference for ZODB we already do the same - specify egg-version for all

ZEO[test] requires ZopeUndo, but we now never pin that anywhere in e.g. stack/slapos.cfg .
