TESTS: move tests/*.cfg to tests/config

These are a collection of test files for a variety of features (old or
more recent). 2 or 3 files were found lying there non-committed and
were moved at the same time. A few deprecated or obsolete keywords were
updated to their recent equivalent. Many of these configurations are
made to trigger different parsing errors so it is normal that plenty
of them fail.

Now the tests directory is cleaner and easier to navigate through.
