Fix up a bunch of our license statements and add SPDX most places

The license statements in our source files were getting to be a giant
mess, and mostly they all just say the same thing.  I've switched most
of it to SPDX labels, but left copyright statements in place (where they
were not obviously incorrect copy-paste jobs that I did...).

If there's some change here you don't think is valid, let me know and
we can fix it up together.
