Other changes:
- Refactor based on -devel port ([no autotools](https://gitlab.freedesktop.org/xorg/xserver/-/commit/9de9c3127325))
- Assume maintainership (critical for a lot of my ports)
NOTE: -devel still has more bugfixes, see https://gitlab.freedesktop.org/xorg/xserver/-/compare/xwayland-21.1...master
IMPORTANT: This is still a prototype. I'm not very interested in standalone releases if those only have superficial QA while the main work happens in `master` as opposed to dedicated `xwayland` branch. For example, if real bugfixes are gated on release schedule (2 per year) with no window for patch-level releases then the value proposition is negative.
