Fixed bug 2082 - SDL stdlib implementation does not force upper case for %X format specifier

norfanin

When SDL_vsnprintf handles the %x format specifier, a boolean is set to signal forced lower case. It also should be able to signal forced upper case for the %X specifier. A boolean is not sufficient anymore. The attached patch adds an enum for the three cases: lower, upper and no change.
