Namespaces in C

In C you can create pseudo-namespaces by abusing structs of function pointers, making function calls look like module.func(x) instead of func(x).

A lot of people online spout that this creates overhead, but this should show that clang>=15.0.7 will still inline such function calls. GCC 11.3.1 is unable to inline the function, but will still call the function directly.
