This avoids code duplication and provides variable-size support
for BLAKE2s like 786b9a8
Test data obtained with libb2 with the following programs:
==> b2.c <==
#include <blake2.h>
#include <unistd.h>
int main() {
char buf[16] = {};
blake2s(buf, 0, 0, 16, 0, 0);
write(1, buf, 16);
}
==> b3.c <==
#include <blake2.h>
#include <unistd.h>
int main() {
char buf[10] = {};
blake2s(buf, "\x61", 0, 10, 1, 0);
write(1, buf, 10);
}
