I think we should -- while strlcpy() is not standardized, it is widely
used (in libc on all the BSDs, Solaris and OS X, as well as private
copies in Linux, glib, etc.).
A wholesale replacement of strncpy() calls is probably worth doing --
replacing them with strlcpy() if the source string is NUL-terminated,
and I suppose memcpy() otherwise.
