Svn repository recovery

The svn repository was moved to read-only on 20/01/2020. The "missing" commits consisted in:

• Commits from Nebil Ayape Katcho, Javier Gonzalez Platas and Juan Rodriguez Carvajal, that were discarded after discussion with Juan
• 1 commit from Thierry Roisnel, that was already integrated in GitLab (commit f35ae159)
• 3 commits from Alain Filhol, that have been added into GitLab
