I am unsure about:

* use_atomic

* use_threads

At least those two I need them for the threading plugin which I have poured some work into #830 and is now mature enough, which I have used to implement multi-threaded file search and threaded find project file for now. And the performance gains are measurable at least on my slower ARM64 box with 2T Cortex-A53 and 4T Cortex-A73

force pushede to trigger the CI and detect some faults.

One find indicates we need to enabled events until the following issue is resolved.
libsdl-org/SDL#5413

After a whole heap of 3 releases among which the entire meson.build had been reworked, OS and compiler specific bugs had been fixe and my will to live start my Windows VM had been completely depleted

This is ready

I briefly tested this while testing #915 , works just fine.

OK, good enough for me. Resolving conflict and merging.
