Daniel Kurtz 5c2e2a164d os/xprintf: add Xvscnprintf and Xscnprintf ...

Normal snprintf() usually returns the number of bytes that would have been
written into a buffer had the buffer been long enough.

The scnprintf() variants return the actual number of bytes written,
excluding the trailing '\0'.
