*: manual SPDX License ID conversions

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".
