test: port Documentation/Xz/Audit/ErrorHandler/PharArchiver tests as stubs

All ignored/todo!(): they need infrastructure not yet ported (console
Application, HttpDownloader/curl, ApplicationTester, PHP runtime error
handler, PharData/ZipArchive). Wires up the downloader test target.
setUp/tearDown not ported.
