instead of using hard coded divisions to calculate ram stats it's better to use macros defined in config.h. BSD port was doing this already, using macros defined in it's common.h header. I pulled those macros out and applied them to all platforms. File version.h.in got renamed into config.h.in since it doesn't caontain only the version anymore.
