Functions
int	n_random_bytes (unsigned char *buf, size_t n)
	fill buf with n cryptographically secure random bytes (getrandom(2) when available, otherwise /dev/urandom).
static int	n_random_from_urandom (unsigned char *buf, size_t n)
N_STR *	n_random_hex_token (size_t nbytes)
	generate nbytes secure random bytes and return them as a lowercase hex N_STR (2*nbytes characters); free with free_nstr.
