This commit makes all symbols that are not part of the API Interface,
or used only in the object files where they are defined, static.
Causing the following benefits:
- The compiler can resolve functions for better performance
- The library size is decreased
NOTE: Spec file generators need to be adjusted for newer spec's to not do the same mistakes again
