This reverts commit 6c399134.

This is not really specific to python2, it is specific to ERP5, now that
ERP5 uses python3, the naming became not really good

This reverts 1b291415 (component/ghostscript: Workaround for slaprunner
paths with double slashs, 2021-06-02) and 4e9a9cf1 (component/tesseract:
Workaround for slaprunner paths with double slashs, 2021-08-19). We no
longer support slappruner and these commits were causing issues on
python3

statsmodels and websocket-client were pinned to Python3-only versions,
and slapos.toolbox was installed in develop mode from a Python3-only
revision.

fixup ac38a241 (Increase maximum ISO size to 20GB in KVMs., 2024-06-07)

With buildout3 all python2 software must extend this

Some Linux distributions, in particular server distributions such
as RHEL or SLE, have ISOs that are above 10GB in size.
This commits updates the maximum ISO size from 10GB to 20GB, so that
these ISOs can be used when requesting a new KVM.

In 55449aca (software/erp5: describe the allowed formats for family
and frontend names, 2024-01-01) we changed to a stricter definition of
zope and frontends partitions names, but because these objects allowed
additional properties, a partition not matching the pattern would be
anyway be accepted.

ptyprocess=0.6.0 uses flit as build backend

  The script were failing to generating the proof but it was continuing anyway.
  the set -e forces the script exit.

  This diff don't cause error since bash isn't run with -e but makes write_backup_proof useless basically.

pkgutil-resolve-name=1.3.10 requires flit_core as build backend.

This is used by component/slapos.

Use older numpy=1.22.0 to remain compatible with statsmodel=0.11.1.
Use older setuptools=44.1.1 to be able to install numpy=1.22.0.

dnspython=2.1.0 requires poetry as build backend.

Older Theia versions no longer compile inside test nodes since we
prevent using the system python.

Remove obsolete upgrade tests since we now upgrade from a Theia
version after merge request !1399.

Export (theia0) and export (theia1, ...) instances published
connection parameters twice, once without and once with the
resiliency connection parameters. Keep only that last one.

Use official SOAPpy=0.12.22 compatible with pip.
Downgrade zope.authentication=4.5.0 because 5.0 requires Python>=3.7.

When using slapos.reboostrap to re-launch buildout with the version
of Python that was just installed, zc.buildout and its dependencies
are reinstalled for the new Python with the same egg versions. Thus
SRs which install Python 2 need to use Python-2-compatible versions
of setuptools, pip and wheel all along.

For this stack/slapos-py2.cfg is introduced.

It is also used to move all

```
[openssl]
<= openssl-1.1
```

from individual Python2 SRs to a common place.

Except for python2: keep beautifulsoup4=4.8.2.

beautifulsoup4=4.12.2 requires flit as build backend.

backcall=0.2.0 requires flit-core as build backend

entrypoints=0.3 rquires flit as build backend

pkgconfig=1.5.1 requires poetry as build backend.

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.

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

Version up slapos.rebootstrap to adapt to buildout3.

Some phones with Android 12+ disconnects from
5G networks which don't support IMS. Therefore
we add minimal IMS support in this commit (even
though we don't actually need it's features).

Only Amarisoft >= 2024-05-02 support launching
lteims without root privilege, so if Amarisoft
version is older IMS is disabled and we inform
the user so in the connection parameters.

For this to work, SIM cards config needs to be
modified, impu and impi must be for instance:
impu: 001010000001312,
impi: 001010000001312@ims.mnc001.mcc001.3gppnetwork.org

 - pycrypto does not seem used (because it does not work on py3 with buildout3)
 - cns.recipe.symlink and PyRSS2Gen versions are defined in stack/slapos.cfg

Revert eb1b1a41 to avoid the use of
`fPIC` flag as it is a "contagious" build option.

To not face the build error "relocation R_X86_64_32 against
.rodata.str1.8 can not be used when making a shared object; recompile
with -fPIC" while building a shared library without fPIC flag, `gcc` is
compiled with `-enable-default-pie` flag (which is a compilation option
used for `gcc` binaries provided by Debian by example, see `gcc -v`).
