- Replaced the whole directory with current source. This adds a few more
  scripts that we could remove again if desired, but it's easier just to
  be able to copy everything.
- However, the new test directory requires c++11, which travis doesn't
  have, so it's ditabled.
- The invocation of configure had to lose the CONFIG_FILES= param,
  because with that set, configure would fail to create the Makefile
  which in turn caused the whole thing to fail.
