Add missing libxcb to rpath

This reverts commit ca5ba490.

It's actually a good idea to update our pandas version (0.19.x is
already 7 years old, in one project we recently run into a bug of this
pandas version).

We only need to prepare erp5 with few changes so that it also support
those newer versions. This preperation was done in nexedi/erp5!1738.

/reviewed-on nexedi/slapos!1355

using ERP5: nexedi/erp5!1545

See merge request nexedi/slapos!1122

1) stack/erp5/zope-versions.cfg
2) stack/slapos.cfg
3) component/ZODB/buildout.cfg.

and remove stack/erp5/ztk-versions.cfg as we need only small part of it.

stack/slapos.cfg should be listed in the begining of software release extends list.

ERP5 now only supports WSGI

This needs a recent enough erp5, with the following commit:
zopewsgi: configure threads count and large_file_threshold with argparse

We only support wsgi now.

TODO: revert nexedi/slapos.package@63da524b

Only wsgi is supported with Zope 4

haufe.requestmonitoring already supports WSGI and Python3 and seems
used and maintainted.

For ZEO4, this was implemented as a monkey patch in ERP5, but this is
now supported in ZEO5, but not enabled by default.

The setting is only avaiable through ZEO's own ZConfig, but not with
ZODB's <zeoclient> so we also adjust the config to import ZEO and use
ZEO's <clientstorage>.

SIGUSR2 for reopening log files was handled by ZServer and waitress does not
handle signals at all, so we could handle this signal but Zope official
documentation recommends using logrotate `copytruncate`:
  https://zope.readthedocs.io/en/4.7/zopebook/MaintainingZope.html#log-rotation
  https://github.com/zopefoundation/Zope/issues/809

This was using `python` which is not always available

Also re-export package-lock.json for the format from npm we currently
have in theia

Compile xdpyinfo for use, in case of debug.

bash tests files (*..bash) was not included to nxdtest.

See merge request nexedi/slapos!1365

Shorten the socket path
Add a promise to check socket

This updates python extension to a version supporting only python3.

To have full python2 support, it's possible to download
https://open-vsx.org/extension/ms-python/python/2020.10.332292344
and use "Install from VSIX" option and manually apply the patch to fix
perfomance issue with buildout paths:

    curl https://lab.nexedi.com/nexedi/slapos/raw/bdb7777beb34d8840cbbc498adba7a55d521079b/component/theia/ms-python-disable-jedi-buildout.patch | patch  ~/tmp/vscode-unpacked/ms-python.python-2020.10.332292344.vsix/extension/pythonFiles/lib/python/jedi/inference/sys_path.py

Set this as default version, there was no default version before.

This also introduce a step to download the tarball headers for node-gyp,
otherwise it will download it directly bypassing libnetworkcache.

- MariaDB 10.3.38 & 10.4.28
- mroonga 13.00
- groonga 13.0.0
- groonga-normalizer-mysql 1.2.1

We stopped using it because of 2 data integrity issues:
- https://jira.percona.com/browse/PS-5569 ("FT index corrupt")
- https://jira.percona.com/browse/PS-4291 ("DELETE sometimes do nothing")

TokuDB is also already disabled because transparent huge pages are
enabled by default.
