This change is a proof of concept on how to easily integrate existing tests from the tools/regression/ hierarchy into the /usr/tests/ test suite and on how to adapt them to the new layout for src. To achieve these goals, this change: - Moves tests from tools/regression/bin/<tool>/ to bin/<tool>/tests/. - Renames the previous regress.sh files to legacy_test.sh. - Adds Makefiles to build and install the tests and all their supporting data files into /usr/tests/bin/. - Plugs the legacy_test test programs into the test suite using the new TAP backend for Kyua (appearing in 0.8) so that the code of the test programs does not have to change. - Registers the new directories in the BSD.test.dist mtree file.
