build: Automatically parse version from tag
The build will now parse tags so the git tag is now the single source
of truth for a version. We do not need to manually maintain the
version header.
The VERSION file uses git's export-subst feature. When git archive
creates a snapshot (e.g. cgit), git substitutes the $Format:...$
placeholder with the output of git describe, embedding the version
string directly in the archive. This requires the export-subst
attribute to be set for the VERSION file in the repository's
.gitattributes.
The version is resolved in the following order:
- git describe (inside a git repository with tags)
- the VERSION file (archives/snapshots)
- 0.0.0 (fallback)
The build system will warn when it can't set a correct version, such
as in a git repo without tags, or an archive without VERSION.
