[PATCH 00/12] c99: use more designated initializers

A follow-up to 404c4a54624 (Merge branch 'ab/designated-initializers', 2021-10-11) and a4b9fb6a5cf (Merge branch 'ab/designated-initializers-more', 2021-10-18). These code readability improvements are something we can allow ourselves now that we have a hard dependency on C99.

These changes merge cleanly with "seen", so they should be easy to deal with as far as anything else that's in-flight goes.
