Internal Refactoring for better thread safety

[markus2330]

As the API discussions are still ongoing and an agreement on the full API will probably take some time (I still suggest to pick smaller changes which have a clear problem), I suggest that you start with internal refactoring to get the development of the refactoring tool going so that we see what it actually can do.

Following points came to my mind:

• Replace non-thread-safe functions #4870
  usage of thread safe functions everywhere, especially strerror_r. Systematically search for all occurrences of POSIX functions that have a _r version (can be found out with apropos).
• toml should be reentrant #4466
  Imho this is the most important problem, which leads to easily reproducible crashes if two threads do something with KDB. I am not sure, however, if and how automatic refactoring can be helpful there.
• Remove global variables #4869
  search for all global variables. If there are any, please report and let us discuss if automatic refactoring makes sense.

usage of thread safe functions everywhere

Yes, that seems like a pretty good showcase example.

Imho the most important problem is

If you're using TOML and see it as an important problem, why not create a PR yourself? The issue already suggests what needs to be done and it shouldn't be too hard to do.

In any case, even if this could be automated, I think doing it by hand is much quicker and easier.

search for all global variables

Finding global variables should work with plain tree-sitter, no need for the tool I'm working on. Refactoring probably can't be automated here either, since what should be done very much depends on what the variable is used for. The only thing that might be automatable would be adding thread_local, but that might not work for all cases and also needs C11 (which I'm not sure if we want to require).
