Ichthyostega 3caa5cfb03 Tests: reorganise test folders
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
