use a consistent style for fixed-size int types The stdint.h types don't cover 128-bit integers and the underscore makes them ill suited to usage in function suffixes. Instead, use the common naming style in the Linux kernel and elsewhere including the ChaCha8 implementation included here. 2018-10-04 23:55:16 +05:30			`#include "util.h"`
