feat(fls): write the file systems of a .fls, loaded by Java as the original

Browse Source

topologyWriter.ts adds each node's file tree to the root its constructor
makes, as XMLEncoder does (arbeitsVerzeichnis, files as new Datei(name,
typ, inhalt)); a root of its own is set anew.

The reader now reads the files of routers and home routers too: their
constructor makes files from templates (the web interface), and the file
adds to them (a web server's www.conf). systemSoftware.ts keeps what the
file adds, and templateFiles says whether the constructor's files stay in
front (false when the file sets a root of its own). The topology test finds
our part at the end of Java's tree and the template in front, the same for
every router of a class across the corpus.

Checked by Java against Java: every corpus file, read and written again,
loads with the same file systems as the original. The synthetic topology
adds a nested tree with a renamed root, a nameless directory, a file
without type, content with CR, CRLF and beyond-BMP characters, router files
after the template and a home router with a root of its own. 9 mutation
probes, each loaded by Java, were all caught.
