This resolves a long-standing issue: we could not use proper include paths for test-helper code that was defined alongside the tests. Since some test-helper code must now be relocated into the »Vault«-Layer, I took the opportunity to finally resolve this annoyance. The solution is two-fold * introduce a dedicated test-support library * remove the quirks that were necessary to support some plain-C tests Together, this allows to raise the include-directory by one level, and then to adjust all folder names so that they match the namespace
