xorg-server 21.1.21 freshly released to fix some annoying regressions

For those of you still rocking xorg rather than Wayland, there's a new release out that should hopefully fix up some issues you may have been seeing. There was a security advisory back in October for more issues that were fixed, and a small bug-fix after that - so this release follows on from those.

What's changed in this release? From the release announcement:

The changes being reverted here are part of a series of changes previously backported in the stable branch, yet these are not actual fixes to address bugs found in the stable branch, while those changes introduced regressions with reverse PRIME with the NVIDIA closed-source driver, issues with 10-bit output with the AMDGPU driver and reduced performance with the AMDGPU driver.

The changes:

Olivier Fourdan (6):
Revert "glamor: reject configs using unsupported rgbBits size"
Revert "glamor_egl: add support of GlxVendorLibrary option"
Revert "xorg: initialize glamor provider"
Revert "glamor: Lift the GLX EGL backend from Xwayland"
Revert "glamor: add glvnd_vendor private"
xserver 21.1.21

Your distribution (if it still packages xorg) should hopefully pull in the update sometime soon.
