Since upgrading to zc.buildout = 3.0.1+slapos004, slapos.rebootstrap
and slapos.recipe.template tests are failing due to: these two tests
running buildout, buildout installing develop eggs, develop eggs now
being installed with pip install -e instead of setup.py develop, and
pip install -e launching sys.executable -E at some point. This fails
because the tests are run using gpython:main script, which currently
does not support -E option.

As a quick fix run these two tests with a barebone python executable
and use export PYTHONPATH to provide the needed eggs. This is not as
good as gpython:main because PYTHONPATH will be inherited by all sub
processes and not just those launched with sys.executable, including
potentially other versions of python.

Old GCC versions wrongly patched `__has_include` directives in system
includes (using fixincludes).
This was reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91085,
and patches to fix this behavior are given in
https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=6bf383c37e6131a8e247e8a0997d55d65c830b6d
and are applied upstream in versions above 12.1.
This commit applies these patches to older GCC versions.

This bug in GCC's fixincludes manifest itself with several seemingly
unrelated symptoms.
In particular, there are two conflicting "mount.h" includes, one coming
from Linux and other from Glibc.
Newer Glibc included some preprocessor tricks to detect if the Linux
header has been previously included and prevent incompatibilities by not
redefining common symbols, thus allowing its header to be included
*after* the Linux header.
In case that the header is included *before* the Linux header, it uses
the aforementioned `__has_include` directive to detect and include the
Linux header before itself if present, thus preventing its inclusion
afterwards.
However, due to the `fixincludes` wrong substitution, the check was
always false, and thus including the Glibc header before the Linux one
caused the compilation to fail, with an error similar to:

This error was originally detected in Nexedi in
nexedi/slapos@fe60394b (comment 189391)
by @vpelletier, but no action was taken at the time to solve it.
Some of its symptoms were detected and fixed individually in
nexedi/slapos!1579 and
nexedi/slapos!1580 ,
by reordering the includes, but the above error in libmount, which could
not be solved that easily, made me delve more into the problem and find
the root cause.

This test checks that running `slapos node software` command on theia
shell starts installing software, but this command might get an error
like:

    process started, but another slapos process is aleady running with pid 2656158, exiting

this happened for example with https://erp5js.nexedi.net/#/test_result_module/20240911-ED8B4BF9/60

zeo uses temporary files during commit, we want to keep these temporary
files in its partition.
The reason which motivated this change was to prevent problems when
system /tmp is full. It's also consistent to how we configure other
services.

This test uses XMLRPC to control ERP5

this logic was simple enough to be inlined and this makes it easier to
make changes

- Each class now correspond to an instance with different configuration,
and possibly several test methods.
- Upgraded to more recent pypdf version.
- The code has been reviewed to reduce complexity and repetition.
- Adds documentation to all public functions, in Google style.
- Some other cosmetic changes have been made for
consistency (consistent parentheses indentation, consistent string
literal quotes), courtesy of ruff.

The `enable-scripting` parameter allows to specify a LibreOffice script
to be applied before saving the document, as per
cloudooo@a09d87af
If false (the default), an exception will be raised instead.

This commit also adds two SlapOS integration tests classes to test the
functionality:
- TestScripting requests an instance with scripting enabled, and tests
the scripting functionality.
- TestScriptingDisabled tests that scripting fails if it is not enabled
explicitly.

The option "ooo_enable_scripting" can now be set up in the
generic.cloudooo recipe.
This option allows the Cloudooo server to execute user scripts to edit
the documents before they are saved
(see cloudooo@a09d87af).

When using older GCC versions (e.g. 8.3.0), Inkscape fails with an error
similar to:

```C++
/srv/slapgrid/slappart15/srv/runner/instance/slappart7/tmp/shared/inkscape/31c6ae5c72c5325d479cca38e62b82bb/.build/inkscape-1.3.2_2023-11-25_091e20ef0f/src/ui/tools/booleans-subitems.cpp: In lambda function:

     auto ranf = [&] { return std::uniform_real_distribution()(gen); };
```

This may be an instance of this problem:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81486

In any case, setting a minimum version of 10.5 for GCC when building
Inkscape, as done in this commit, seems to fix this.

This is based on example from https://json-schema.org/understanding-json-schema/reference/object#unevaluatedproperties
this approach allows extending a schema from another software type with
some extra properties while rejecting other properties on instances,
like it's done with additionalProperties: false.

Currently librsync 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 librsync to always use the lib directory.
