forked from Dniel97/segatools
This change deletes the GetProcAddress hook and exports symbols corresponding to the hooked functions from each hook DLL instead; we stop at redirecting LoadLibrary/GetModuleHandle calls to the hook DLL. This simplified approach has less hidden magic going on behind the scenes and is more readily composable (i.e. a hook DLL can export redirect symbols for more than one dynamically-loaded DLL).
