test: port SecurityAdvisoryPoolFilter, downloader/command/app stubs

All ignored/todo!(): the advisory filter parses affectedVersions via a
look-around regex; the Hg/Fossil/Perforce/Archive downloaders and
RepositoryManager need mocked process/HttpDownloader (curl); the Validate/
Archive commands, ApplicationTest and CompletionFunctionalTest need the
ApplicationTester/console harness. setUp/tearDown not ported.
