Opinionated xstrlcpy changes (#513)
* 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.
