[PATCH 0/7] Structed output versioning support

[Austin Clements]

This series obsoletes [0] and must be applied on top of the Emacs CLI
error handling series [1].  This is much simpler than the original
series because it no longer includes the Emacs CLI error handling.
This also switches to a CLI-wide minimum version instead of a
per-command version, prints a warning if an old but still supported
version is requested to ease client maintenance, and renames
--use-schema to --format-version (which parallels --format better and
simplifies error text).
