Use MIT license instead of CC0 CC0 has continued to fall out of favor due to the patents clause (https://lwn.net/ml/fedora-legal/CAC1cPGw1xScGAXo-0NRs92zFB7ptRxTt=oCYi0BxfZDfAgUtYQ@mail.gmail.com). Years ago I released some source files in this project (not the whole project) under CC0. Use the MIT license for these files instead. Note that this requires claiming copyright on the latest version of these files. Of course, previous versions of these files remain public domain where legally recognized; this is *not* in any way an attempt to "revoke" the public domain status of previous versions.
COPYING: clarify the license Some of the language in COPYING is potentially unclear. For example, there is some ambiguity in when each license option of GPL and LGPL is allowed. Clarify the language. Note, this commit isn't intended to actually change the license at all. It just clarifies what I intended.
COPYING: adjust word choice
Use more comprehensive public domain dedications
COPYING: updates and clarifications
Update COPYING - Use "or later" clause for GPLv3 and LGPLv3 - Make LGPL exception more general
Update library license: Add LGPLv3 exception
