Subject: [PATCH 1/3] cpu.h: use standard types instead of glib's
Future commits will introduce standard C code that
wants to use cpu.h. Let's convert cpu.h to standard
types.
I'm choosing not to change the gui code that uses
cpu.h though. I think that in all platforms where
glib is supported, guint64 should always be uint64_t
and guint should always be unsigned int.
