Gilles Peskine 7dc97048d6 Revert "Remove tests that depend on TLS or X.509" 
This reverts commit 9afb2e9921.

Conflicts:
* include/CMakeLists.txt
  * "Make config.h available" comment: there has been a change
    adjacent to where it was removed. Just re-add what was removed.
* tests/CMakeLists.txt:
  * compat.sh: there has been a change immediately before where it was
    removed. Just re-add what was removed.
