Change the build options to use “hidden” visibility by default, and mark only the symbols that are part of the public API with the COG_API macro. This prevents library private symbols from leaking to the global symbol namespace even if they are not declared as “static”, and also makes the ELF PLT smaller which prevents accidental symbol overriding and improves load times.
