caucase.sh does not work with openssl 1.1

TrafficServer is recent enough to work on any make, not only the old one.

So that when the path change, typically after switching the instance to
a new slapos software release, the wrapper gets automatically reinstalled.

Because wrapper recipe uses the same technique as zc.recipe.egg
scripts with sys.path , it needs the same technique of depending of
buildout paths in options.

After trying to upgrade the components using libxml2 I went back to just backporting minimal patches for the following reasons:
 - mariadb 10.4 is EOL but we are not fully ready to use newer versions in ERP5.
 - updating inkscape needs gcc > 10 but scipy py2 needs gcc < 10 and we do not have an easy way of using more than one gcc version in a software
 - gdal is used only in an old projects still using python2, so updating it too early and depending on py3 seemed not usefull.
 - I don't understand why this started to appear now, but libreoffice does not start because of a libc version mismatch, it was still using icu from the system, so this also includes a fix to use slapos' icu

This happens with python3 chained exceptions tracaback

This saves almost 20Go of disk space

we are seeing errors like this:

also re-organise the multi version

it seems better to not let pipe error pass through

A typo in 8ebd8949 (stack/wendelin: Introduce mariadb replication,
2024-10-30) cause the timezones to not be loaded and caused a warning
on the script:

./bin/mariadb-on-startup: 31: mysql_tzinfo_to_sql: not found

This was depending on a side effect of slapos.recipe.template of
creating the intermediate folder structure so that it is here for
subsequent slapos.recipe.build:download sections

Using slapos.recipe.build is a bit more explit

template & rendered work, but they are legacy options

such convention is understood by nxdbom

This disables the use of shared memory which caused process to hang

Avoid crashing buildout when mariadb dump backups are disabled and
publish an empty replication-bootstrap-url instead.

Set the non configurable timeouts to better values, especially for the active
connection, so that it's possible to download big files from slow backends
(let it transfer for 2 days).

Drop proxy.config.http.down_server.abort_threshold, as it's removed from
version 9.x
