Updated inet_addr.c, inet_ntoa.c, inet_ntop.c, and inet_pton.c to follow the same approach, ensuring POSIX compliance while integrating Windows function signatures via dynamic loading. Modified function pointer declarations and signatures to align with Windows API documentation. Created ws_types.h for function pointer type definitions, ensuring Windows API compatibility and keeping the POSIX interface. Refined the wsaapi.h header to define appropriate calling conventions and helper types, and removed the Windows-specific header, switching to ws_types.h for function pointer compatibility.
