* lib/fs, lib/model: Improve filesystem operations during tests (fixes #5422) Introduces MustFilesystem that panics on errors and should be used for operations during testing which must never fail. Create temporary directories outside of testdata. * don't do a filesystem, just a wrapper around os for testing * fix copyright
