SPDX is an ISO standard for describing licenses in a computer readable format, which is useful when applying license compliance tools and the like to source code. In addition to ensuring that the Wuffs C distribution is properly annotated to the benefit of projects using Wuffs and SPDX-supporting tools, add it everywhere else where there's a license in this repo for consistency, too.
