grub_getsize is ambiguous (size of what?) and grub_getgeometry suggests a 
function to get the geometry of a GUI window, grub_get_term_size is better. 
What do you think?

Would it be better for grub_getxy and grub_getsizexy (or whatever it is 
called) to handle the case of null pointers, rather than the terminal 
drivers?

I also noticed I omitted to change term/i386/pc/vga.c. I will fix this.

 to `grub_gotoxy' changed to unsigned, `grub_getxy' returns values
 via pointers to unsigned as above.
