The files converted in this commit either had some random misspelling or formatting weirdness that made them escape automated replacement, or have a particularly "weird" licensing setup (e.g. dual-licensed.) This also marks a bunch of "public domain" files as SPDX License "NONE". Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
