List of include files from the standard library (or not) that are safe to use

[WEREMSOFT]

When creating an app, it's safe to use stdint.h, you can not use stdio.h. What about string.h or math.sh?

It will be great if we can create a list of safe headers that we can use, or an alternative (like if we decide to implement an equivalent for the context we are running in).

This will help to migrate existing programs or libraries to the ecosystem. I think it will be nice to have a good collection of utilities that can help people to develop stuff on it.

Also, it will be good if we have implementations of stuff, to have a completion rate associated. Let's say, I create malloc and free as a stack alocator, and free will only free memory if the section is in the top of the stack. Well that is usefull to implement a library like stb_image, but it can create problems if used intensively, so it will have a completion rate of "barely acceptable".
