Review libc dependencies and remove when possible
Just for clarification, no plans to remove libc dependency, just did some code analysis to see how much raylib depend on stardard C library. My conclusions:
- stdlib.h: primary dependency is for malloc() and free()
- stdio.h: primary dependency is for FILE access, maybe it could go through a custom ABI?
- string.h: just around 8 functions required
- math.h: just around 8 functions required
- others: 1-2 functions required for some other headers
