qemu_{put|get}_{16,32,64}s takes an unsigned pointer, signed variables 
produce a warning. Since most of the variables are actually ints, I 
reverted to use qemu_{put|get}_{16,32,64} (without the 's' and using the 
value instead of the pointer). This fixes those warnings. I couldn't get 
the point why only the pointer version was used throughout all files, so 
I expect some resistance here...
