"%llu" replaced with "%" PRIu64

On some architectures, uint64_t is defined as:

typedef unsigned long long int __u64;

on another architectures as:

typedef unsigned long int __u64;

So, according to man 3 printf,
uint64_t should be printed as "%llu" on some architectures, and as "%lu" on another. The same for scanf.

To eliminate that challenge, there is inttypes.h, in which appropriate constants
are defined for current architecture.

32-bit types (and even 16 and 8 bit types) should be printed using such constants if
printed variable defined as uint_XXXt or intXXXt type. But in reality 32-bit and less
types does not gain run-time error (except in scanf), because they pushed to stack as
32-bit values at least. So, I decide not to fix that.
