Add tests from the old svn tree

We're losing the svn history (which we could probably keep if we tried
hard enough) but don't consider that worthwhile.

Note these tests are destructive, so run them only in a throwaway
environment like a chroot, container, or vm.

The tests/run.all script should be the one which launches all the tests.
