Pawel "l0ner" Soltys d3eb9e3187 use macros from config.h to calculate megabyes
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.
