Make C-extension Ractor-safe

[mohamedhafez]

In planning ahead to the near future when TruffleRuby can run C-extensions marked with rb_ext_ractor_safe(true) in parallel, and for when Ractors are no longer just experimental, it would be great if the C-extension could be made Ractor-safe, or marked as such if it already is so!

That seems reasonable, do you want to have a go at making a PR?

[mohamedhafez]

Unfortunately I don't know the first thing about programming in C personally 😅 And to be honest I just don't have the bandwith to figure it out

@ioquatix I actually got a PR merged into trilogy, and have one pending for puma after having a maintainer comment on an issue that it would be welcome and shouldn't cause issues. I would be happy to send one in here if you or another maintainer could take a quick look and make sure there isn't any global state being used, and that things should already be Ractor-safe (unfortunately I don't have the background in C-extensions to really be able to do that myself). If you give me the all-clear, I'd love to send in a similar PR here!

Sure, I'd be totally happy with that and can help merge and release it.
