Then '-o' is POSIX complient too, but shellcheck thinks it's "not well defined".

* Unvectorize xstrlcpy

On all libcs I could find, memcpy does a better job than we can.

* Rename xstrlcpy to xstrsncpy to avoid confusion

The semantics of our xstrlcpy differed slightly from strlcpy; we return
the number of copied characters; strlcpy returns the strlen(src).
strscpy from Linux is similar except it returns the number of copied
characters sans the NUL byte, so this is named strsncpy to be different.
