fix signedness of UINT32_MAX and UINT64_MAX at the preprocessor level
per the rules for hexadecimal integer constants, the previous definitions were correctly treated as having unsigned type except possibly when used in preprocessor conditionals, where all artithmetic takes place as intmax_t or uintmax_t. the explicit 'u' suffix ensures that they are treated as unsigned in all contexts.
